Alpha Release 0.8.0

Changes from 0.7.0:

This release adds support for opening multiple windows at once.

Lua Changes:

• Added an optional parameter for specifying the name of a GameScene a GameObject/EventListener belongs to. This also applies to BoxObject, MenuObject and TextObject.
• Added LineObject, which draws lines of characters on the screen.
• Added utility functions to translate between data indices, row/column and pixel position.
• The timestep in Loop is now given in milliseconds (ms).

C++ Changes:

• Removed object proxies in favor of using unique_ptr for owning objects, and raw pointers for references in Lua.
• Amended Audio, EventListener, GameObject and TimedFunction classes to derive from a BaseObject class, which are stored in a singular list.
• Added debug information to all classes that derive from BaseObject, and to the application. This currently includes the time taken to update the objects.
• Added a GameScene class that encompasses a Window, FontAtlas and Background. This allows multiple windows to be created.
• Changed shaders/Shader into the ShaderProgram class, which is stored in a GameScene and now supports uniforms.
• Changed views/View into the CharacterMap class, which is stored in a GameScene.
• Extracted the texture-related features of FontAtlas and Background into a Texture class.
• Added a TexturePacker, to pack font bitmaps and other images into a single texture.
• Moved the static PlaySound function in objects/Audio into it's own file.
• Added Seek and Rewind functions to object/Audio.
• Removed Resume, and Play no longer rewinds to the start of the audio in objects/Audio.
• Removed GetIntervalElapsed from timing/Timer.
• Added the option to decide if a Window should hide itself, close or quit the program when a user closes it.
• Added the option to set a Window's title.
• Amended the following parameters to be stored as a vec4:
  • CharacterParams colours
  • Background colours
  • Window clear colours
• Fixed EventListeners possibly being inactive upon creation.
• Added TimedFunctions, used to delay/repeat code execution by a set amount of time.
• Amended Object:set to require a Character as a return value, rather than having to set through code.
• Rearranged some files to (hopefully) make more sense. See below for details.

Other Changes:

• Removed MS Visual Studio build support.

File re-arrangement:

The primary reasons for rearranging files are for a couple of reasons:

1. There really isn't a distinction between objects and resources.
2. I dislike having folders that will only have 1 file/class in them. The shaders folder is an exception, as it will contain more shader-related code in a later release.

Rearranged files include:

• Moving application/Application into the root folder.
• Splitting the EventListener class from events/Listener into objects/EventListener.
• Renaming logging/Logger into utility/SpdlogUtils.
• Moving resources/Audio into the objects folder.
• Renaming objects/Object into objects/GameObject.
• Moving objects/Character, resources/Background, resources/FontAtlas and resources/Window into the rendering folder.
• Moving shaders/ShaderProgram into rendering/ShaderProgram.
• Renaming system/DebugFunctions into utility/DebugUtils.
• Moving system/miniaudio.cc and system/stbi.cc into the vendor folder.
