-# Changelog:
-
-## 0.1.3 - 15/02/2018
-
-**Enhancements:**
-
-*Mouse cursor:*
-- Added the ability to hide the mouse cursor
-- Added the ability to lock the mouse cursor to the window
-
-
-## 0.1.2 - 18/12/2017
-
-**Bug Fixes:**
-- Resolved issue with string destruction after storing the texture in the cache  
-
-
-## 0.1.1 - 06/12/2017
-
-**Bug Fixes:**
-- Fixed issue when applying a scale to rotated sprites
-- Fixed issue where it was not possible to obtain the sprite's dimensions
-- Fixed issue where the texture cache would not empty when the game exits but the textures would be unloaded from GPU
-- Fixed issue where FPS counter could be rendered behind other sprites 
-
-**Enhancements:**
-
-*Sprites:*
-- Sprites now use appropriate getters and setters
-- Sprites can now be flipped in the x or y axis. 
-- Sprites can now use a source rectangle to make use of sprite sheets
-- Sprites now support for opacity using the alpha channel
-
-*Render modes:*
-- Batching modes for texture, front to back and back to front mode added
-- Borderless window support added
-- Deferred rendering support added
-- Fullscreen support added
-- Implemented a new sprite batch class that manages rendering of both text and sprites
-- Rendering the FPS also shows some additional debug info
-- Replaced dynamic text buffers with a larger static buffer
-- Replaced sprite shader with an instancing version
-
-*Documentation:*
-- Doxygen comments have been added to all public facing API classes and functions.
-
-*Misc:*
-- Added a new demo browser to the game engine
-- Huge performance increases when rendering large numbers of sprites
-- Huge performance increases when rendering large amounts of text
-- Ordering renders by their texture and colour hugely benefits the sprite batch system
-
-
-**Upgrades:**
-- Updated GLEW to 2.1.0
-
-
-**Known Issues:**
-- Mouse coordinates are in screen space when using bordless mode and not orthogonal

-	//! Base class of most objects of the irrKlang.
-	/** This class provides reference counting through the methods grab() and drop().
-	It also is able to store a debug string for every instance of an object.
-	Most objects of irrKlang are derived from IRefCounted, and so they are reference counted.
-
-	When you receive an object in irrKlang (for example an ISound using play2D() or
-	play3D()), and you no longer need the object, you have 
-	to call drop(). This will destroy the object, if grab() was not called
-	in another part of you program, because this part still needs the object.
-	Note, that you only don't need to call drop() for all objects you receive, it
-	will be explicitely noted in the documentation.
-
-	A simple example:
-
-	If you want to play a sound, you may want to call the method
-	ISoundEngine::play2D. You call
-	ISound* mysound = engine->play2D("foobar.mp3", false, false true);
-	If you no longer need the sound interface, call mysound->drop(). The 
-	sound may still play on after this because the engine still has a reference
-	to that sound, but you can be sure that it's memory will be released as soon
-	the sound is no longer used.
-
-	If you want to add a sound source, you may want to call a method
-	ISoundEngine::addSoundSourceFromFile. You do this like
-	ISoundSource* mysource = engine->addSoundSourceFromFile("example.jpg");
-	You will not have to drop the pointer to the source, because
-	sound sources are managed by the engine (it will live as long as the sound engine) and
-	the documentation says so.

- * \section intro Introduction
- *
- * Welcome to the irrKlang API documentation. This page should give you a short overview 
- * over irrKlang, the high level audio library. 
- * In this documentation files you'll find any information you'll need to develop applications with
- * irrKlang using C++. If you are looking for a tutorial on how to start, you'll
- * find some on the homepage of irrKlang at
- * <A HREF="http://www.ambiera.com/irrklang" >http://www.ambiera.com/irrklang</A>
- * or inside the SDK in the directory \examples.
- *
- * The irrKlang library is intended to be an easy-to-use 3d and 2d sound engine, so
- * this documentation is an important part of it. If you have any questions or
- * suggestions, please take a look into the ambiera.com forum or just send a mail.
- *

- *
- *
- * \section features Features of irrKlang
- *
- * irrKlang is a high level 2D and 3D 
- * cross platform sound engine and audio library.
- * It has a very simply object orientated interface and was designed to be used
- * in games, scientific simulations, architectural visualizations and similar.
- * irrKlang plays several file formats such as
- * <ul>
- *               <li>RIFF WAVE (*.wav)</li>
- *               <li>Ogg Vorbis (*.ogg)</li>
- *               <li>MPEG-1 Audio Layer 3 (*.mp3)</li>
- *               <li>Free Lossless Audio Codec (*.flac)</li>
- *               <li>Amiga Modules (*.mod)</li>
- *               <li>Impulse Tracker (*.it)</li>
- *               <li>Scream Tracker 3 (*.s3d)</li>
- *               <li>Fast Tracker 2 (*.xm)</li>        
- * </ul>
- * It is also able to run on different operating systems and use several output drivers:
- *<ul>
- *       <li>Windows 98, ME, NT 4, 2000, XP, Vista, Windows 7, Windows 8</li>
- *	<ul>
- *       <li>DirectSound</li>
- *       <li>DirectSound8</li>
- *       <li>WinMM</li>
- *	</ul>
- *       <li>Linux / *nix</li>	
- *	<ul>
- *       <li>ALSA</li>
- *	</ul>
- *  <li>MacOSX (x86 and PPC)</li>
- *	<ul>
- *       <li>CoreAudio</li>
- *	</ul>
- * </ul>

-  * \section tipsandtricks Tips and Tricks
- *
- * This section lists a few tips you might consider when implementing the sound part of your application
- * using irrKlang:
- *
- * <ul>
- *               <li>If you can choose which audio file format is the primary one for your application,
- *					 use .OGG files, instead of for example .MP3 files. irrKlang uses a lot less memory
- *                   and CPU power when playing .OGGs.</li>
- *               <li>To keep your application simple, each time you play a sound, you can use for example
- *                   play2D("filename.mp3") and let irrKlang handle the rest. There is no need to implement
- *                   a preloading/caching/file management system for the audio playback. irrKlang will handle
- *                   all this by itself and will never load a file twice. </li>
- *               <li>irrKlang is crashing in your application? This should not happen, irrKlang is pretty stable,
- *                   and in most cases, this is a problem in your code: In a lot of cases the reason is simply
- *                   a wrong call to irrklang::IRefCounted::drop(). Be sure you are doing it correctly. (If you are unsure,
- *                   tempoarily remove all calls to irrklang::IRefCounted::drop() and see if this helps.)</li>

- *
- * \section concept Starting up the Engine
- *
- * irrKlang is designed so that it is very easy to achieve everything, its interface should
- * be very simple to use. The @ref quickstartexample shows how to play and mp3 file, and there
- * is another example, @ref quickstartexample2, showing some few more details.<br/>
- * To start up the sound engine, you simply need to call createIrrKlangDevice(). To shut it down,
- * call IRefCounted::drop():
- *
- * \code
- * #include <irrKlang.h>
- *
- * // ...
- *
- * // start up the engine
- * irrklang::ISoundEngine* engine = irrklang::createIrrKlangDevice();
- *	
- * // ...
- * 
- * // after finished,
- * // close the engine again, similar as calling 'delete'
- * engine->drop(); 
- * \endcode
- *
- * The createIrrKlangDevice() function also accepts several parameters, so that you can 
- * specify which sound driver should be used, if plugins should be used, if irrKlang
- * should run in multithreaded mode, and similar.
- * <br/>
- * <br/>
- * <br/>
- * <br/>
- *
- *
- *
- * \section playingSounds Playing Sounds
- *
- * Once you have irrKlang running (like in @ref concept), you can start playing sounds:
- *
- * \code
- * engine->play2D("someSoundFile.wav"); 
- * \endcode
- *
- * This works with all supported file types. You can replace "someSoundFile.wav" with
- * "someSoundFile.mp3", or "someSoundFile.ogg", for example.<br/>
- * To play a sound looped, set the second parameter to 'true':
- *
- * \code
- * engine->play2D("myMusic.mp3", true); 
- * \endcode 
- *
- * To stop this looping sound again, use engine->\link irrklang::ISoundEngine::stopAllSounds stopAllSounds()\endlink to stop all sounds, or
- * irrklang::ISound::stop() if you only want to stop that single sound. @ref changingSounds
- * shows how to get to that ISound interface.
- * <br/>
- * <br/>
- * <br/>
- * <br/>
- *
- *
- * \section changingSounds Influencing Sounds during Playback
- * To influence parameters of the sound such as pan, volume or playback speed during runtime, 
- * to get the play position or stop playback of single playing sounds,
- * you can use the irrklang::ISound interface. 
- * irrklang::ISoundEngine::play2D (but also play3D) returns
- * a pointer to this interface when its third ('startPaused') or fourth ('track') parameter
- * was set to true:
- *
- * \code
- * irrklang::ISound* snd = engine->play2D("myMusic.mp3", true, false, true); 
- *
- * // ...
- *
- * if (snd)
- *     snd->setVolume(someNewValue);
- * 
- * // ...
- * 
- * if (snd)
- * {
- *     snd->drop(); // don't forget to release the pointer once it is no longer needed by you
- *     snd = 0;
- * }
- * \endcode
- *
- * The irrklang::ISound interface can also be used to test if the sound has been finished, 
- * set event receivers, pause and unpause sounds and similar. 
- * <br/>
- * <br/>
- * <br/>
- * <br/>
- *
- *
- * \section soundSources Using Sound Sources
- *
- * To be more flexible playing back sounds, irrKlang uses the concept of sound sources. 
- * A sound source can be simply the name of a sound file, such as "sound.wav". It is possible
- * to add "sound.wav" as sound source to irrKlang, and play it using the sound source pointer:
- *
- * \code
- * irrklang::ISoundSource* shootSound = engine->addSoundSourceFromFile("shoot.wav"); 
- *
- * engine->play2D(shootSound);
- *
- * // note: you don't need to drop() the shootSound if you don't use it anymore
- * \endcode
- *
- * The advantage of using irrklang::ISoundSource is that it is possible to set 
- * default values for this source, such
- * as volume or distances if it should be used as 3D sound:
- *
- * \code
- * irrklang::ISoundSource* shootSound = engine->addSoundSourceFromFile("shoot.wav"); 
- *
- * shootSound->setDefaultVolume(0.5f);
- *
- * // shootSound will now be played with half its sound volume by default:
- * engine->play2D(shootSound);
- * \endcode
- *
- * It is also possible to have multiple settings for the same sound file:
- *
- * \code
- * irrklang::ISoundSource* shootSound = engine->addSoundSourceFromFile("shoot.wav"); 
- * irrklang::ISoundSource* shootSound2 = engine->addSoundSourceAlias(shootSound, "silentShoot"); 
- *
- * shootSound2->setDefaultVolume(0.1f);
- *
- * // shootSound will now be played with 100% of its sound volume by default,
- * // shootSound2 will now be played 10% of its sound volume by default. It is 
- * //  also possible to play it using engine->play("silentShoot"), now.
- * \endcode
- *
- * Using addSoundSourceFromMemory(), it is also possible to play sounds back directly from memory,
- * without files.
- * Of course, it is not necessary to use sound sources. Using irrklang::ISound, it is
- * possible to change the settings of all sounds, too. But using sound sources, it is
- * not necessary to do this every time a sound is played.
- * <br/>
- * <br/>
- * <br/>
- * <br/>
- *
- *
- *
- * \section sound3d 3D Sound
- *
- * There is nothing difficult in playing sounds in 3D using irrKlang: Instead of using 
- * irrklang::ISoundEngine::play2D(), just use irrklang::ISoundEngine::play3D(), which
- * takes a 3D position as additional parameter:
- *
- * \code
- * irrklang::vec3df position(23,70,90);
- * engine->play3D("yourSound.wav", position);
- * \endcode
- *
- * But to make it sound realistic, you need to set a minimal sound
- * distance: If your sound is caused by a bee, it will usually have a smaller
- * sound radius than for example a jet engine. You can set default values using sound sources
- * (see @ref soundSources) or set these values after you have started the sound paused:
- *
- * \code
- * irrklang::vec3df position(23,70,90);
- *
- * // start the sound paused:
- * irrklang::ISound* snd = engine->play3D("yourSound.wav", position, false, true);
- *
- * if (snd)
- * {
- *    snd->setMinDistance(30.0f); // a loud sound
- *    snd->setIsPaused(false); // unpause the sound
- * }
- * \endcode
- * 
- * There is also the possibility to change the maxDistance, but it is only necessary to change this
- * in very rare cicumstances.
- * If the sound moves, it is also a good idea to update its position from time to time:
- * 
- * \code
- * if (snd)
- *    snd->setPosition(newPosition);
- * \endcode
- *
- * And don't forget to drop() the sound after you don't need it anymore. If you do, it's 
- * nothing severe because irrKlang will still clean up the sounds resources after it has
- * finished, but you still would waste some few bytes of memory:
- * 
- * \code
- * if (snd)
- * {
- *    snd->drop();
- *    snd = 0;
- * }
- * \endcode
- *
- * To update the position of yourself, the listener of the 3D sounds, use this from
- * time to time:
- *
- * \code
- * irrklang::vec3df position(0,0,0);        // position of the listener
- * irrklang::vec3df lookDirection(10,0,10); // the direction the listener looks into
- * irrklang::vec3df velPerSecond(0,0,0);    // only relevant for doppler effects
- * irrklang::vec3df upVector(0,1,0);        // where 'up' is in your 3D scene
- *
- * engine->setListenerPosition(position, lookDirection, velPerSecond, upVector);
- * \endcode
- *
- * <br/>
- * <br/>
- * <br/>
- * <br/>
- *
- *
- * \section removingSounds Removing Sounds
- *
- * irrKlang manages the memory usage of sounds by itself, so usually, you don't have
- * to care about memory management. But if you know you need to reduce the
- * amount of used memory at a certain point in your program, you can do this:
- *
- * \code
- * engine->removeAllSoundSources(); 
- * \endcode
- *
- * This will remove all sounds and also cause all sounds to be stopped. To remove single
- * sounds from the engine, use:
- *
- * \code
- * engine->removeSoundSource(pointerToSomeSoundSource); 
- * // or:
- * engine->removeSoundSource("nameOfASoundFile.wav"); 
- * \endcode
- *
- * Note: Only removing buffered sounds will reduce the amount of memory used by irrKlang, streamed
- * sounds don't occupy a lot of memory when they are not played.
- * <br/>
- * <br/>
- * <br/>
- * <br/>
- *
- *
- *
- * \section events Using Sound Events
- *
- * In order to wait for a sound to be finished, it is simply possible to 
- * poll irrklang::ISound::isFinished(). Another way would be to constantly use 
- * irrklang::ISoundEngine::isCurrentlyPlaying to test wether a sound with that name or source
- * is currently playing. But of course, an event based approach is a lot nicer. That's why irrKlang
- * supports sound events.<br/>
- * The key to sound events is the method 
- * \link irrklang::ISound::setSoundStopEventReceiver setSoundStopEventReceiver \endlink
- * of the irrklang::ISound interface
- * (See @ref changingSounds on how to get the ISound interface):
- *
- * \code
- * irrklang::ISound* snd = engine->play2D("speech.mp3", false, false, true); 
- * if (snd)
- *    snd->setSoundStopEventReceiver(yourEventReceiver, 0);
- * \endcode
- * 
- * The optional second parameter of setSoundStopEventReceiver is a user pointer, set it to whatever you like.
- * 'yourEventReceiver' must be an implementation of the irrklang::ISoundStopEventReceiver interface.<br/>
- * A whole implementation could look like this:
- *
- * \code
- * class MySoundEndReceiver : public irrklang::ISoundStopEventReceiver
- * {
- *   public:
- *     virtual void OnSoundStopped (irrklang::ISound* sound, irrklang::E_STOP_EVENT_CAUSE reason, void* userData)
- *     {
- *        // called when the sound has ended playing
- *        printf("sound has ended");
- *     }
- * }
- *
- * // ...
- *
- * MySoundEndReceiver* myReceiver = new MySoundEndReceiver();
- * irrklang::ISound* snd = engine->play2D("speech.mp3", false, false, true); 
- * if (snd)
- *    snd->setSoundStopEventReceiver(myReceiver);
- *
- * myReceiver->drop(); // similar to delete
- * \endcode
- * 
- * The irrklang::ISoundStopEventReceiver::OnSoundStopped() method is guaranteed to be called when a sound or sound stream has stopped,
- * either because the sound reached its playback end, its sound source was removed,
- * ISoundEngine::stopAllSounds() has been called or the whole engine was deleted.
- * <br/>
- * <br/>
- * <br/>
- * <br/>
- *
- *
- *
- * \section memoryPlayback Memory Playback
- *
- * Using irrKlang, it is easily possible to play sounds directly from memory instead out of 
- * files. There is an example project showing this: In the SDK, in /examples/03.MemoryPlayback.
- * But in short, it simply works by adding the memory as sound source (See @ref soundSources for 
- * details about sound sources):
- *
- * \code
- * engine->addSoundSourceFromMemory(pointerToMemory, memorySize, "nameforthesound.wav");
- * 
- * // play sound now
- * engine->play2D("nameforthesound.wav");
- * \endcode
- *
- * Or using a sound source pointer:
- *
- * \code
- * irrklang::ISoundSource* snd = 
- *   engine->addSoundSourceFromMemory(pointerToMemory, memorySize, "nameforthesound.wav");
- * 
- * // play sound now
- * engine->play2D(snd);
- * \endcode
- *
- * Note: It is also possible to overwrite the file access directly, don't use this Memory Playback
- * feature for this. See @ref fileOverriding for details.
- * <br/>
- * <br/>
- * <br/>
- * <br/>
- *
- *
- *
- * \section effects Sound Effects
- *
- * irrKlang supports the effects Chorus, Compressor, Distortion, Echo, Flanger
- * Gargle, 3DL2Reverb, ParamEq and WavesReverb, when using the sound driver 
- * irrklang::ESOD_DIRECT_SOUND_8, which selected by default when using Windows.<br/>
- *
- * Using the irrklang::ISound interface, you can optain the irrklang::ISoundEffectControl
- * interface if the sound device supports sound effects and the last parameter ('enableSoundEffects')
- * was set to true when calling play2D():
- *
- * \code
- * irrklang::ISound* snd = engine->play2D("sound.wav", true, false, true, ESM_AUTO_DETECT, true);
- *
- * if (snd)
- * {
- *    irrklang::ISoundEffectControl* fx = snd->getSoundEffectControl();
- *    if (fx)
- *    {
- *        // enable the echo sound effect for this sound
- *        fx->enableEchoSoundEffect();
- *    }
- * }
- * 
- * snd->drop();
- * \endcode
- *
- * This enabled the echo sound effect for this sound. The method also supports a lot of 
- * parameters, and can be called multiple times to change those parameters over time if wished.
- * There are a lot of other sound effects, see irrklang::ISoundEffectControl for details.
- * <br/>
- * <br/>
- * <br/>
- * <br/>
- *
- *
- *
- * \section fileOverriding Overriding File Access
- *
- * It is possible to let irrKlang use your own file access functions.
- * This is useful if you want to read sounds from other sources than
- * just files, for example from custom internet streams or 
- * an own encypted archive format. There is an example in the SDK in 
- * examples/04.OverrideFileAccess which shows this as well.<br/>
- *
- * The only thing to do for this is to implement your own  irrklang::IFileFactory,
- * and set it in irrKlang using irrklang::ISoundEngine::addFileFactory():
- *
- * \code
- * // a class implementing the IFileFactory interface to override irrklang file access
- * class CMyFileFactory : public irrklang::IFileFactory
- * {
- *   public:
- *
- *   // Opens a file for read access. Simply return 0 if file not found.
- *   virtual irrklang::IFileReader* createFileReader(const ik_c8* filename)
- *   {
- *     // return your own irrklang::IFileReader implementation here, for example like that:
- *     return new CMyReadFile(filename);
- *   }
- * };
- * 
- * // ...
- *
- * CMyFileFactory* myFactory = new CMyFileFactory();
- * engine->addFileFactory(myFactory);
- * myFactory->drop();
- * \endcode
- *
- * For a full example implementation, just take a look into the SDK in examples/04.OverrideFileAccess.
- * <br/>
- * <br/>
- * <br/>
- * <br/>
- *
- *
- *
- * \section audioDecoders Adding Audio Decoders
- *
- * To add support for new file formats, it is possible to add new audio decoders
- * to irrKlang. 
- * The only thing to do for this is to implement your own  irrklang::IAudioStreamLoader,
- * and irrklang::IAudioStream, and set it in irrKlang using 
- * irrklang::ISoundEngine::registerAudioStreamLoader():
- *
- * \code
- * class NewAudioStreamLoader : public irrklang::IAudioStreamLoader
- * {
- *   // ... returns NewAudioDecoder and the used file name suffices.
- * };
- *
- * class NewAudioDecoder : public irrklang::IAudioStream
- * {
- *   public:
- *     // ... decodes the new file format
- * };
- *
- * // ...
- *
- * NewAudioDecoder* loader = new NewAudioDecoder();
- * engine->registerAudioStreamLoader(loader);
- * loader->drop();
- * \endcode
- * 
- * There is an example audio decoder and loader with full source in plugins/ikpMP3, which
- * adds MP3 audio decoding capabilities to irrKlang.
- * <br/>
- * <br/>
- * <br/>
- * <br/>
- *
- *
- *
- * \section plugins Creating irrKlang Plugins
- *
- * irrKlang plugins are ikp*.dll (Windows), ikp*.so (Unix) or ikp*.dylib (MacOS) 
- * files which are loaded by irrKlang at startup when the 
- * irrklang::ESEO_LOAD_PLUGINS was set (which is default) or
- * irrklang::ISoundEngine::loadPlugins() was called. <br/>
- *
- * The plugin only needs to contain the following function which will be called by irrKlang:
- *
- * \code
- * #ifdef WIN32
- * // Windows version
- * __declspec(dllexport) void __stdcall irrKlangPluginInit(ISoundEngine* engine, const char* version)
- * #else
- * // Linux and Mac OS version
- * void irrKlangPluginInit(ISoundEngine* engine, const char* version)
- * #endif
- * {
- *   // your implementation here
- * }
- * \endcode
- *
- * In there, it is for example possible to extend irrKlang with new audio decoders,
- * see @ref audioDecoders for details. <br/>
- * 
- * There is an example plugin with full source in plugins/ikpMP3, which
- * adds MP3 audio decoding capabilities to irrKlang.
- * <br/>
- * <br/>
- * <br/>
- * <br/>
- *
- *
- *
- * \section staticLib Using irrKlang as static Lib
- *
- * If you don't want to use the irrKlang.DLL file and link irrKlang statically, you can do this
- * by simply linking to the irrKlang.lib in the bin/win32-visualstudio_lib folder. This folder
- * will only available in the pro versions of irrKlang, which you get when purchasing an irrKlang
- * license.
- *
- * To use irrKlang in this way, just define IRRKLANG_STATIC before including irrklang.h, like this:
- *
- * \code
- * #define IRRKLANG_STATIC
- * #include <irrKlang.h>
- * \endcode
- *
- * Of course, IRRKLANG_STATIC can also simply be defined in the project/compiler settings instead of
- * in the source file.
- * <br/>
- * <br/>
- * <br/>
- * <br/>
- *
- *
- *
- * \section enumeratingDevices Enumerating sound devices
- *
- * irrKlang uses the default sound device when playing sound when started without parameters. But if you want
- * irrKlang to playback sound on one specific sound device, you may want to enumerate the available
- * sound devices on your system and select one of them. Use irrklang::createSoundDeviceList() for this. 
- * This example code shows how to print a list of all available sound devices on the current system and lets
- * the user choose one of them: 
- *
- * \code
- * int main(int argc, const char** argv)
- * {
- *	// enumerate devices
- * 
- * 	irrklang::ISoundDeviceList* deviceList = createSoundDeviceList();
- * 
- * 	// ask user for a sound device
- * 
- * 	printf("Devices available:\n\n");
- * 
- * 	for (int i=0; i<deviceList->getDeviceCount(); ++i)
- * 		printf("%d: %s\n", i, deviceList->getDeviceDescription(i));
- * 
- * 	printf("\nselect a device using the number (or press any key to use default):\n\n");
- * 	int deviceNumber = getch() - '0';
- * 
- * 	// create device with the selected driver
- * 
- * 	const char* deviceID = deviceList->getDeviceID(deviceNumber);
- * 		
- * 	ISoundEngine* engine = createIrrKlangDevice(irrklang::ESOD_AUTO_DETECT, 
- * 	                                            irrklang::ESEO_DEFAULT_OPTIONS,
- * 	                                            deviceID);
- * 
- * 	deviceList->drop(); // delete device list
- *
- *  // ... use engine now
- * } 
- * \endcode
- *
- * In this way, it is also possible to play back sound using two devices at the same time: Simply 
- * create two irrKlang devices with each a different deviceID.<br/>
- * Note: createSoundDeviceList() takes a driver type parameter (such as irrklang::ESOD_DIRECT_SOUND8), which you
- * have to set to the same value as the first parameter you want to use with createIrrKlangDevice(), if it is 
- * other than irrklang::ESOD_AUTO_DETECT.
- * <br/>
- * <br/>
- * <br/>
- * <br/>
- *
- *
- *
- * \section recordingAudio Recording Audio
- *
- * irrKlang is able to record audio from sound capturing devices such as microphones (currently only 
- * supported in windows). Use the irrklang::IAudioRecorder interface to do this. The following example shows how
- * to record some audio and play it back again using the engine: 
- *
- * \code
- * int main(int argc, const char** argv)
- * {
- *	irrklang::ISoundEngine* engine = irrklang::createIrrKlangDevice();
- *	irrklang::IAudioRecorder* recorder = irrklang::createIrrKlangAudioRecorder(engine);
- *
- *	if (!engine || !recorder)
- *	{
- *		printf("Could not create audio engine or audio recoder\n");
- *		return 1;
- *	}
- *
- *	printf("\nPress any key to start recording audio...\n");
- *	getch();
- *
- *	// record some audio
- *
- *	recorder->startRecordingBufferedAudio();
- *
- *	printf("\nRECORDING. Press any key to stop...\n");
- *	getch();
- *
- *	recorder->stopRecordingAudio();
- *
- *	printf("\nRecording done, recorded %dms of audio.\n", 
- *		recorder->getAudioFormat().FrameCount * 1000 / recorder->getAudioFormat().SampleRate );
- *	printf("Press any key to play back recorded audio...\n");
- *	getch();
- *
- *	// play the recorded audio
- *	recorder->addSoundSourceFromRecordedAudio("myRecordedVoice");
- *	engine->play2D("myRecordedVoice", true);
- *
- *	// wait until user presses a key
- *	printf("\nPress any key to quit...");
- *	getch();
- *
- *	recorder->drop();
- *	engine->drop(); // delete engine
- *
- *	return 0;
- * } 
- * \endcode
- *
- * In order to select a specific audio capturing device for recording, it is necessary to enumerate
- * the available devices. Simply replace the first to lines of code of the example above with code
- * like this to list all devices and select one:
- *
- * \code
- *  // enumerate recording devices and ask user to select one
- * 
- *  irrklang::ISoundDeviceList* deviceList = irrklang::createAudioRecorderDeviceList();
- *
- *  printf("Devices available:\n\n");
- *
- *  for (int i=0; i<deviceList->getDeviceCount(); ++i)
- *           printf("%d: %s\n", i, deviceList->getDeviceDescription(i));
- *
- *  printf("\nselect a device using the number (or press any key to use default):\n\n");
- *  int deviceNumber = getch() - '0';
- *
- *  // create recording device with the selected driver
- *
- *  const char* deviceID = deviceList->getDeviceID(deviceNumber);
- *  irrklang::ISoundEngine* engine = irrklang::createIrrKlangDevice();
- *  irrklang::IAudioRecorder* recorder = 
- *     irrklang::createIrrKlangAudioRecorder(engine, irrklang::ESOD_AUTO_DETECT, deviceID);
- *
- * \endcode
- *
- * <br/>
- * <br/>
- * <br/>
- * <br/>
- *
- *
- * \section unicode Unicode support
- *
- * irrKlang supports unicode on all operating systems. Internally, it uses UTF8, and all functions accepting strings
- * and file names take UTF8 strings. If you are running irrKlang on Windows, and are using the UNICODE define or using
- * wchar_t* strings directly, you can do this as well. Use the irrKlang provided function makeUTF8fromUTF16string() to 
- * convert your wchar_t* string to a char* string.
- *
- * This example shows how:
- *
- * \code
- * const wchar_t* yourFilename = L"SomeUnicodeFilename.wav"; // assuming this is the file name you get from some of your functions
- *
- * const int nBufferSize = 2048; // large enough, but best would be wcslen(yourFilename)*3.
- * char strBuffer[nBufferSize]; 
- * irrklang::makeUTF8fromUTF16string(yourFilename, strBuffer, nBufferSize);
- *
- * // now the converted file name is in strBuffer. We can play it for example now:
- * engine->play2D(strBuffer);
- * \endcode
- *
- * Of course, you can use any other unicode converion function for this. makeUTF8fromUTF16string() is only provided
- * for convenience.

- * \section quickstartexample Quick Start Example
- *
- * To simply start the engine and play a mp3 file, use code like this:
- *
- * \code
- * #include <iostream>

-@brief exception indicating a parse error
-
-This exception is thrown by the library when a parse error occurs. Parse errors
-can occur during the deserialization of JSON text, CBOR, MessagePack, as well
-as when using JSON Patch.
-
-Member @a byte holds the byte index of the last read character in the input
-file.
-
-Exceptions have ids 1xx.

-name / id                      | example message | description
------------------------------- | --------------- | -------------------------
-json.exception.parse_error.101 | parse error at 2: unexpected end of input; expected string literal | This error indicates a syntax error while deserializing a JSON text. The error message describes that an unexpected token (character) was encountered, and the member @a byte indicates the error position.
-json.exception.parse_error.102 | parse error at 14: missing or wrong low surrogate | JSON uses the `\uxxxx` format to describe Unicode characters. Code points above above 0xFFFF are split into two `\uxxxx` entries ("surrogate pairs"). This error indicates that the surrogate pair is incomplete or contains an invalid code point.
-json.exception.parse_error.103 | parse error: code points above 0x10FFFF are invalid | Unicode supports code points up to 0x10FFFF. Code points above 0x10FFFF are invalid.
-json.exception.parse_error.104 | parse error: JSON patch must be an array of objects | [RFC 6902](https://tools.ietf.org/html/rfc6902) requires a JSON Patch document to be a JSON document that represents an array of objects.
-json.exception.parse_error.105 | parse error: operation must have string member 'op' | An operation of a JSON Patch document must contain exactly one "op" member, whose value indicates the operation to perform. Its value must be one of "add", "remove", "replace", "move", "copy", or "test"; other values are errors.
-json.exception.parse_error.106 | parse error: array index '01' must not begin with '0' | An array index in a JSON Pointer ([RFC 6901](https://tools.ietf.org/html/rfc6901)) may be `0` or any number without a leading `0`.
-json.exception.parse_error.107 | parse error: JSON pointer must be empty or begin with '/' - was: 'foo' | A JSON Pointer must be a Unicode string containing a sequence of zero or more reference tokens, each prefixed by a `/` character.
-json.exception.parse_error.108 | parse error: escape character '~' must be followed with '0' or '1' | In a JSON Pointer, only `~0` and `~1` are valid escape sequences.
-json.exception.parse_error.109 | parse error: array index 'one' is not a number | A JSON Pointer array index must be a number.
-json.exception.parse_error.110 | parse error at 1: cannot read 2 bytes from vector | When parsing CBOR or MessagePack, the byte vector ends before the complete value has been read.
-json.exception.parse_error.112 | parse error at 1: error reading CBOR; last byte: 0xF8 | Not all types of CBOR or MessagePack are supported. This exception occurs if an unsupported byte was read.
-json.exception.parse_error.113 | parse error at 2: expected a CBOR string; last byte: 0x98 | While parsing a map key, a value that is not a string has been read.
-
-@note For an input with n bytes, 1 is the index of the first character and n+1
-      is the index of the terminating null byte or the end of file. This also
-      holds true when reading a byte vector (CBOR or MessagePack).

-json.exception.invalid_iterator.201 | iterators are not compatible | The iterators passed to constructor @ref basic_json(InputIT first, InputIT last) are not compatible, meaning they do not belong to the same container. Therefore, the range (@a first, @a last) is invalid.
-json.exception.invalid_iterator.202 | iterator does not fit current value | In an erase or insert function, the passed iterator @a pos does not belong to the JSON value for which the function was called. It hence does not define a valid position for the deletion/insertion.
-json.exception.invalid_iterator.203 | iterators do not fit current value | Either iterator passed to function @ref erase(IteratorType first, IteratorType last) does not belong to the JSON value from which values shall be erased. It hence does not define a valid range to delete values from.
-json.exception.invalid_iterator.204 | iterators out of range | When an iterator range for a primitive type (number, boolean, or string) is passed to a constructor or an erase function, this range has to be exactly (@ref begin(), @ref end()), because this is the only way the single stored value is expressed. All other ranges are invalid.
-json.exception.invalid_iterator.205 | iterator out of range | When an iterator for a primitive type (number, boolean, or string) is passed to an erase function, the iterator has to be the @ref begin() iterator, because it is the only way to address the stored value. All other iterators are invalid.
-json.exception.invalid_iterator.206 | cannot construct with iterators from null | The iterators passed to constructor @ref basic_json(InputIT first, InputIT last) belong to a JSON null value and hence to not define a valid range.
-json.exception.invalid_iterator.207 | cannot use key() for non-object iterators | The key() member function can only be used on iterators belonging to a JSON object, because other types do not have a concept of a key.
-json.exception.invalid_iterator.208 | cannot use operator[] for object iterators | The operator[] to specify a concrete offset cannot be used on iterators belonging to a JSON object, because JSON objects are unordered.
-json.exception.invalid_iterator.209 | cannot use offsets with object iterators | The offset operators (+, -, +=, -=) cannot be used on iterators belonging to a JSON object, because JSON objects are unordered.
-json.exception.invalid_iterator.210 | iterators do not fit | The iterator range passed to the insert function are not compatible, meaning they do not belong to the same container. Therefore, the range (@a first, @a last) is invalid.
-json.exception.invalid_iterator.211 | passed iterators may not belong to container | The iterator range passed to the insert function must not be a subrange of the container to insert to.
-json.exception.invalid_iterator.212 | cannot compare iterators of different containers | When two iterators are compared, they must belong to the same container.
-json.exception.invalid_iterator.213 | cannot compare order of object iterators | The order of object iterators cannot be compared, because JSON objects are unordered.
-json.exception.invalid_iterator.214 | cannot get value | Cannot get value for iterator: Either the iterator belongs to a null value or it is an iterator to a primitive type (number, boolean, or string), but the iterator is different to @ref begin().

-@brief the JSON type enumeration
-
-This enumeration collects the different JSON types. It is internally used to
-distinguish the stored values, and the functions @ref basic_json::is_null(),
-@ref basic_json::is_object(), @ref basic_json::is_array(),
-@ref basic_json::is_string(), @ref basic_json::is_boolean(),
-@ref basic_json::is_number() (with @ref basic_json::is_number_integer(),
-@ref basic_json::is_number_unsigned(), and @ref basic_json::is_number_float()),
-@ref basic_json::is_discarded(), @ref basic_json::is_primitive(), and
-@ref basic_json::is_structured() rely on it.
-
-@note There are three enumeration entries (number_integer, number_unsigned, and
-number_float), because the library distinguishes these three types for numbers:
-@ref basic_json::number_unsigned_t is used for unsigned integers,
-@ref basic_json::number_integer_t is used for signed integers, and
-@ref basic_json::number_float_t is used for floating-point numbers or to
-approximate integers which do not fit in the limits of their respective type.
-
-@sa @ref basic_json::basic_json(const value_t value_type) -- create a JSON
-value with the default value for a given type

-    @brief scan a number literal
-
-    This function scans a string according to Sect. 6 of RFC 7159.
-
-    The function is realized with a deterministic finite state machine derived
-    from the grammar described in RFC 7159. Starting in state "init", the
-    input is read and used to determined the next state. Only state "done"
-    accepts the number. State "error" is a trap state to model errors. In the
-    table below, "anything" means any character but the ones listed before.
-
-    state    | 0        | 1-9      | e E      | +       | -       | .        | anything

-    minus    | zero     | any1     | [error]  | [error] | [error] | [error]  | [error]
-    zero     | done     | done     | exponent | done    | done    | decimal1 | done
-    any1     | any1     | any1     | exponent | done    | done    | decimal1 | done

-    any2     | any2     | any2     | done     | done    | done    | done     | done
-
-    The state machine is realized with one label per state (prefixed with
-    "scan_number_") and `goto` statements between them. The state machine
-    contains cycles, but any cycle can be left when EOF is read. Therefore,
-    the function is guaranteed to terminate.
-
-    During scanning, the read bytes are stored in token_buffer. This string is
-    then converted to a signed integer, an unsigned integer, or a
-    floating-point number.
-
-    @return token_type::value_unsigned, token_type::value_integer, or
-            token_type::value_float if number could be successfully scanned,
-            token_type::parse_error otherwise
-
-    @note The scanner is independent of the current locale. Internally, the
-          locale's decimal point is used instead of `.` to work with the
-          locale-dependent converters.

-@brief a template for a bidirectional iterator for the @ref basic_json class
-
-This class implements a both iterators (iterator and const_iterator) for the
-@ref basic_json class.
-
-@note An iterator is called *initialized* when a pointer to a JSON value has
-      been set (e.g., by a constructor or a copy assignment). If the iterator is
-      default-constructed, it is *uninitialized* and most methods are undefined.
-      **The library uses assertions to detect calls on uninitialized iterators.**
-
-@requirement The class satisfies the following concept requirements:
--
-[BidirectionalIterator](https://en.cppreference.com/w/cpp/named_req/BidirectionalIterator):
-  The iterator that can be moved can be moved in both directions (i.e.
-  incremented and decremented).
-
-@since version 1.0.0, simplified in version 2.0.9, change to bidirectional
-       iterators in version 3.0.0 (see https://github.com/nlohmann/json/issues/593)

-@tparam Base the base iterator type to reverse. Valid types are @ref
-iterator (to create @ref reverse_iterator) and @ref const_iterator (to
-create @ref const_reverse_iterator).
-
-@requirement The class satisfies the following concept requirements:
--
-[BidirectionalIterator](https://en.cppreference.com/w/cpp/named_req/BidirectionalIterator):
-  The iterator that can be moved can be moved in both directions (i.e.
-  incremented and decremented).
-- [OutputIterator](https://en.cppreference.com/w/cpp/named_req/OutputIterator):
-  It is possible to write to the pointed-to element (only if @a Base is

-// The choice of (alpha,gamma) determines the size of the table and the form of

-// in practice:
-//
-// The idea is to cut the number c * w = f * 2^e into two parts, which can be
-// processed independently: An integral part p1, and a fractional part p2:
-//
-//      f * 2^e = ( (f div 2^-e) * 2^-e + (f mod 2^-e) ) * 2^e

-//              = p1 + p2 * 2^e
-//
-// The conversion of p1 into decimal form requires a series of divisions and
-// modulos by (a power of) 10. These operations are faster for 32-bit than for
-// 64-bit integers, so p1 should ideally fit into a 32-bit integer. This can be
-// achieved by choosing
-//
-//      -e >= 32   or   e <= -32 := gamma
-//
-// In order to convert the fractional part
-//
-//      p2 * 2^e = p2 / 2^-e = d[-1] / 10^1 + d[-2] / 10^2 + ...
-//
-// into decimal form, the fraction is repeatedly multiplied by 10 and the digits
-// d[-i] are extracted in order:
-//
-//      (10 * p2) div 2^-e = d[-1]
-//      (10 * p2) mod 2^-e = d[-2] / 10^1 + ...
-//
-// The multiplication by 10 must not overflow. It is sufficient to choose
-//
-//      10 * p2 < 16 * p2 = 2^4 * p2 <= 2^64.

-    /*!
-    @brief a type for an object
-
-    [RFC 7159](http://rfc7159.net/rfc7159) describes JSON objects as follows:
-    > An object is an unordered collection of zero or more name/value pairs,
-    > where a name is a string and a value is a string, number, boolean, null,
-    > object, or array.
-
-    To store objects in C++, a type is defined by the template parameters
-    described below.
-
-    @tparam ObjectType  the container to store objects (e.g., `std::map` or
-    `std::unordered_map`)
-    @tparam StringType the type of the keys or names (e.g., `std::string`).
-    The comparison function `std::less<StringType>` is used to order elements
-    inside the container.
-    @tparam AllocatorType the allocator to use for objects (e.g.,
-    `std::allocator`)
-
-    #### Default type
-
-    With the default values for @a ObjectType (`std::map`), @a StringType
-    (`std::string`), and @a AllocatorType (`std::allocator`), the default
-    value for @a object_t is:
-
-    @code {.cpp}
-    std::map<
-      std::string, // key_type
-      basic_json, // value_type
-      std::less<std::string>, // key_compare
-      std::allocator<std::pair<const std::string, basic_json>> // allocator_type
-    >
-    @endcode
-
-    #### Behavior
-
-    The choice of @a object_t influences the behavior of the JSON class. With
-    the default type, objects have the following behavior:
-
-    - When all names are unique, objects will be interoperable in the sense
-      that all software implementations receiving that object will agree on
-      the name-value mappings.
-    - When the names within an object are not unique, it is unspecified which
-      one of the values for a given key will be chosen. For instance,
-      `{"key": 2, "key": 1}` could be equal to either `{"key": 1}` or
-      `{"key": 2}`.
-    - Internally, name/value pairs are stored in lexicographical order of the
-      names. Objects will also be serialized (see @ref dump) in this order.
-      For instance, `{"b": 1, "a": 2}` and `{"a": 2, "b": 1}` will be stored
-      and serialized as `{"a": 2, "b": 1}`.
-    - When comparing objects, the order of the name/value pairs is irrelevant.
-      This makes objects interoperable in the sense that they will not be
-      affected by these differences. For instance, `{"b": 1, "a": 2}` and
-      `{"a": 2, "b": 1}` will be treated as equal.
-
-    #### Limits
-
-    [RFC 7159](http://rfc7159.net/rfc7159) specifies:
-    > An implementation may set limits on the maximum depth of nesting.
-
-    In this class, the object's limit of nesting is not explicitly constrained.
-    However, a maximum depth of nesting may be introduced by the compiler or
-    runtime environment. A theoretical limit can be queried by calling the
-    @ref max_size function of a JSON object.
-
-    #### Storage
-
-    Objects are stored as pointers in a @ref basic_json type. That is, for any
-    access to object values, a pointer of type `object_t*` must be
-    dereferenced.
-
-    @sa @ref array_t -- type for an array value
-
-    @since version 1.0.0
-
-    @note The order name/value pairs are added to the object is *not*
-    preserved by the library. Therefore, iterating an object may return
-    name/value pairs in a different order than they were originally stored. In
-    fact, keys will be traversed in alphabetical order as `std::map` with
-    `std::less` is used by default. Please note this behavior conforms to [RFC
-    7159](http://rfc7159.net/rfc7159), because any order implements the
-    specified "unordered" nature of JSON objects.

-    #### Encoding
-
-    Strings are stored in UTF-8 encoding. Therefore, functions like
-    `std::string::size()` or `std::string::length()` return the number of
-    bytes in the string rather than the number of characters or glyphs.
-
-    #### String comparison
-
-    [RFC 7159](http://rfc7159.net/rfc7159) states:
-    > Software implementations are typically required to test names of object
-    > members for equality. Implementations that transform the textual

-    > comparison numerically, code unit by code unit, are interoperable in the

-    > inequality of two strings. For example, implementations that compare
-    > strings with escaped characters unconverted may incorrectly find that
-    > `"a\\b"` and `"a\u005Cb"` are not equal.
-
-    This implementation is interoperable as it does compare strings code unit
-    by code unit.

-    @brief a type for a number (integer)
-
-    [RFC 7159](http://rfc7159.net/rfc7159) describes numbers as follows:
-    > The representation of numbers is similar to that used in most
-    > programming languages. A number is represented in base 10 using decimal
-    > digits. It contains an integer component that may be prefixed with an
-    > optional minus sign, which may be followed by a fraction part and/or an
-    > exponent part. Leading zeros are not allowed. (...) Numeric values that
-    > cannot be represented in the grammar below (such as Infinity and NaN)
-    > are not permitted.
-
-    This description includes both integer and floating-point numbers.
-    However, C++ allows more precise storage if it is known whether the number
-    is a signed integer, an unsigned integer or a floating-point number.
-    Therefore, three different types, @ref number_integer_t, @ref
-    number_unsigned_t and @ref number_float_t are used.
-
-    To store integer numbers in C++, a type is defined by the template
-    parameter @a NumberIntegerType which chooses the type to use.
-
-    #### Default type
-
-    With the default values for @a NumberIntegerType (`int64_t`), the default
-    value for @a number_integer_t is:
-
-    @code {.cpp}
-    int64_t
-    @endcode
-
-    #### Default behavior
-
-    - The restrictions about leading zeros is not enforced in C++. Instead,
-      leading zeros in integer literals lead to an interpretation as octal
-      number. Internally, the value will be stored as decimal number. For
-      instance, the C++ integer literal `010` will be serialized to `8`.
-      During deserialization, leading zeros yield an error.
-    - Not-a-number (NaN) values will be serialized to `null`.
-
-    #### Limits
-
-    [RFC 7159](http://rfc7159.net/rfc7159) specifies:
-    > An implementation may set limits on the range and precision of numbers.
-
-    When the default type is used, the maximal integer number that can be
-    stored is `9223372036854775807` (INT64_MAX) and the minimal integer number
-    that can be stored is `-9223372036854775808` (INT64_MIN). Integer numbers
-    that are out of range will yield over/underflow when used in a
-    constructor. During deserialization, too large or small integer numbers
-    will be automatically be stored as @ref number_unsigned_t or @ref
-    number_float_t.

-    @brief a type for a number (unsigned)
-
-    [RFC 7159](http://rfc7159.net/rfc7159) describes numbers as follows:
-    > The representation of numbers is similar to that used in most
-    > programming languages. A number is represented in base 10 using decimal
-    > digits. It contains an integer component that may be prefixed with an
-    > optional minus sign, which may be followed by a fraction part and/or an
-    > exponent part. Leading zeros are not allowed. (...) Numeric values that
-    > cannot be represented in the grammar below (such as Infinity and NaN)
-    > are not permitted.
-
-    This description includes both integer and floating-point numbers.
-    However, C++ allows more precise storage if it is known whether the number
-    is a signed integer, an unsigned integer or a floating-point number.
-    Therefore, three different types, @ref number_integer_t, @ref
-    number_unsigned_t and @ref number_float_t are used.
-
-    To store unsigned integer numbers in C++, a type is defined by the
-    template parameter @a NumberUnsignedType which chooses the type to use.
-
-    #### Default type
-
-    With the default values for @a NumberUnsignedType (`uint64_t`), the
-    default value for @a number_unsigned_t is:
-
-    @code {.cpp}
-    uint64_t
-    @endcode
-
-    #### Default behavior
-
-    - The restrictions about leading zeros is not enforced in C++. Instead,
-      leading zeros in integer literals lead to an interpretation as octal
-      number. Internally, the value will be stored as decimal number. For
-      instance, the C++ integer literal `010` will be serialized to `8`.
-      During deserialization, leading zeros yield an error.
-    - Not-a-number (NaN) values will be serialized to `null`.
-
-    #### Limits
-
-    [RFC 7159](http://rfc7159.net/rfc7159) specifies:
-    > An implementation may set limits on the range and precision of numbers.
-
-    When the default type is used, the maximal integer number that can be
-    stored is `18446744073709551615` (UINT64_MAX) and the minimal integer
-    number that can be stored is `0`. Integer numbers that are out of range
-    will yield over/underflow when used in a constructor. During
-    deserialization, too large or small integer numbers will be automatically
-    be stored as @ref number_integer_t or @ref number_float_t.
-
-    [RFC 7159](http://rfc7159.net/rfc7159) further states:
-    > Note that when such software is used, numbers that are integers and are
-    > in the range \f$[-2^{53}+1, 2^{53}-1]\f$ are interoperable in the sense
-    > that implementations will agree exactly on their numeric values.
-
-    As this range is a subrange (when considered in conjunction with the
-    number_integer_t type) of the exactly supported range [0, UINT64_MAX],
-    this class's integer type is interoperable.

-
-    #### Default behavior
-

-      the value will be stored as decimal number. For instance, the C++
-      floating-point literal `01.2` will be serialized to `1.2`. During

-    - Not-a-number (NaN) values will be serialized to `null`.

-
-    This implementation does exactly follow this approach, as it uses double
-    precision floating-point numbers. Note values smaller than

-    @brief create a container (array or object) from an initializer list
-
-    Creates a JSON value of type array or object from the passed initializer
-    list @a init. In case @a type_deduction is `true` (default), the type of
-    the JSON value to be created is deducted from the initializer list @a init
-    according to the following rules:
-
-    1. If the list is empty, an empty JSON object value `{}` is created.
-    2. If the list consists of pairs whose first element is a string, a JSON
-       object value is created where the first elements of the pairs are
-       treated as keys and the second elements are as values.
-    3. In all other cases, an array is created.
-
-    The rules aim to create the best fit between a C++ initializer list and
-    JSON values. The rationale is as follows:
-
-    1. The empty initializer list is written as `{}` which is exactly an empty
-       JSON object.
-    2. C++ has no way of describing mapped types other than to list a list of
-       pairs. As JSON requires that keys must be of type string, rule 2 is the
-       weakest constraint one can pose on initializer lists to interpret them
-       as an object.
-    3. In all other cases, the initializer list could not be interpreted as
-       JSON object type, so interpreting it as JSON array type is safe.
-
-    With the rules described above, the following JSON values cannot be
-    expressed by an initializer list:
-
-    - the empty array (`[]`): use @ref array(initializer_list_t)
-      with an empty initializer list in this case
-    - arrays whose elements satisfy rule 2: use @ref
-      array(initializer_list_t) with the same initializer list
-      in this case
-
-    @note When used without parentheses around an empty initializer list, @ref
-    basic_json() is called instead of this function, yielding the JSON null
-    value.
-
-    @param[in] init  initializer list with JSON values
-
-    @param[in] type_deduction internal parameter; when set to `true`, the type
-    of the JSON value is deducted from the initializer list @a init; when set
-    to `false`, the type provided via @a manual_type is forced. This mode is
-    used by the functions @ref array(initializer_list_t) and
-    @ref object(initializer_list_t).
-
-    @param[in] manual_type internal parameter; when @a type_deduction is set
-    to `false`, the created JSON value will use the provided type (only @ref
-    value_t::array and @ref value_t::object are valid); when @a type_deduction
-    is set to `true`, this parameter has no effect
-
-    @throw type_error.301 if @a type_deduction is `false`, @a manual_type is
-    `value_t::object`, but @a init contains an element which is not a pair
-    whose first element is a string. In this case, the constructor could not
-    create an object. If @a type_deduction would have be `true`, an array
-    would have been created. See @ref object(initializer_list_t)
-    for an example.

-    @brief deserialize from an iterator range with contiguous storage
-
-    This function reads from an iterator range of a container with contiguous
-    storage of 1-byte values. Compatible container types include
-    `std::vector`, `std::string`, `std::array`, `std::valarray`, and
-    `std::initializer_list`. Furthermore, C-style arrays can be used with
-    `std::begin()`/`std::end()`. User-defined containers can be used as long
-    as they implement random-access iterators and a contiguous storage.
-
-    @pre The iterator range is contiguous. Violating this precondition yields
-    undefined behavior. **This precondition is enforced with an assertion.**
-    @pre Each element in the range has a size of 1 byte. Violating this
-    precondition yields undefined behavior. **This precondition is enforced
-    with a static assertion.**
-
-    @warning There is no way to enforce all preconditions at compile-time. If
-             the function is called with noncompliant iterators and with
-             assertions switched off, the behavior is undefined and will most
-             likely yield segmentation violation.

-
-    Creates a [JSON Patch](http://jsonpatch.com) so that value @a source can
-    be changed into the value @a target by calling @ref patch function.
-
-    @invariant For two JSON values @a source and @a target, the following code
-    yields always `true`:
-    @code {.cpp}
-    source.patch(diff(source, target)) == target;
-    @endcode
-
-    @note Currently, only `remove`, `add`, and `replace` operations are
-          generated.
-
-    @param[in] source  JSON value to compare from
-    @param[in] target  JSON value to compare against
-    @param[in] path    helper value to create JSON pointers
-
-    @return a JSON patch to convert the @a source to @a target
-
-    @complexity Linear in the lengths of @a source and @a target.

-    @brief applies a JSON Merge Patch
-
-    The merge patch format is primarily intended for use with the HTTP PATCH
-    method as a means of describing a set of modifications to a target
-    resource's content. This function applies a merge patch to the current
-    JSON value.
-
-    The function implements the following algorithm from Section 2 of
-    [RFC 7396 (JSON Merge Patch)](https://tools.ietf.org/html/rfc7396):
-
-    ```
-    define MergePatch(Target, Patch):
-      if Patch is an Object:
-        if Target is not an Object:
-          Target = {} // Ignore the contents and set it to an empty Object
-        for each Name/Value pair in Patch:
-          if Value is null:
-            if Name exists in Target:
-              remove the Name/Value pair from Target
-          else:
-            Target[Name] = MergePatch(Target[Name], Value)
-        return Target
-      else:
-        return Patch
-    ```
-
-    Thereby, `Target` is the current object; that is, the patch is applied to
-    the current value.
-
-    @param[in] patch  the patch to apply
-
-    @complexity Linear in the lengths of @a patch.
-
-    @liveexample{The following code shows how a JSON Merge Patch is applied to
-    a JSON document.,merge_patch}
