* Core : improved the requestAnimFrame usage, and fallback to setInterval. me.sys.useNativeAnimFrame to enable it (disable by default)
* Core : optimized the way objects are managed in the game loop
* Core : defined (and used) a Object.defineProperty function to replace __defineGetter__ / __defineSetter__ (was not supported on IE9/IE10)
* TMX : implemented Tiled "transparency" property for Tileset, allowing to specify which color should be transparent (note: this slows down level loading)
* TMX : fixed unnecessary canvas creation for the collision layer (should free some memory)
* TMX : cleaned/optimized data loading and fixed an issue on FF with XML parsing of "big" Base64 encoded maps (only first nodeValue was parsed by the engine)
* TMX : added support for CSV data encoding
* TMX : added support for flipped tiles, as supported in Tiled 0.7
* TMX : added multiple tileset support
* TMX : added a "background_image" property. To be set through Tiled, and allowing to specify a fix background.
* Entity : merge AnimatedSpriteObject into SpriteObject. SpriteObject now takes an optional additional argument to create an animated sprite
* Entity : added a distanceTo function
* Viewport : fixed camera refresh when changing "deadzone" values
* Loader : added a "onProgress" callback to get progress notification, removing the need to poll the loader each frame for loading progress
* Loader : fix progress notification when TMX files are loaded into the levelDirector
* Loader : added a retry counter for the audio loading : script will now stop and throw an exception after 3 unsuccessful loading attempts.
* Video : renamed "applyEffect" to "applyRGBFilter", and fixed an issue on Opera
* Audio : fixed compatibility issues with IE9/10
* Geometry : added a merge function to me.Rect

0.9.0
* Documentation : API documentation using jsdoc-toolkit (finally!)
* Geometry : define getter for me.Rect coordinates (simplify code)
* Level : support for fadeOut/fadeIn effect in me.LevelEntity (when changing levels)
* Entity : correctly implemented InvisibleEntity Objects (no longer inherit from ObjectEntity)
* Entity : makes SpriteObjet inherit from me.Rect (make it easier to manage sprite pos and size)
* Loader : cosmetic update of the preloader screen
* Viewport : "rounding" issue fix in the viewportEntity (~~30% less CPU usage on Safari/OSX!)
* TMX : cleaned & refactored tilemap collision detection (still not perfect though)

0.8.0
* TMX : support for "TiledObject" (as supported in Tiled 0.6.2)
* Entity : re-factored constructor call to Object Entities (to use the settings obj produced through Tiled)
* Entity : moved collision function from AnimatedSpriteObject to ObjectEntity

0.7.9
* Viewport : added some effects to the camera object (shaking, fading, ...)
* Viewport : re-factored and fixed the camera/viewport code
* Core : re-factored public objects using John Resig Inheritance mechanism.
* Core : fixed the "bootstrap" (unnecessary double call)
* Entity : re-factored parallax code & corrected a bug that was causing the layers to be drawn 2x times
* Audio : partially fix crash audio in safari when audio is enabled
* Core : fixed gfx glitches (rounding issues)
