* The current version of Cocos2d-html5 being used.
* Please DO NOT remove this String, it is an important flag for bug tracking.
* If you post a bug to forum, please attach this flag.
*
* If enabled, the texture coordinates will be calculated by using this formula:
* - texCoord.left = (rect.origin.x*2+1) / (texture.wide*2);
* - texCoord.right = texCoord.left + (rect.size.width*2-2)/(texture.wide*2);
*
* The same for bottom and top.
*
* This formula prevents artifacts by using 99% of the texture.
* The "correct" way to prevent artifacts is by using the spritesheet-artifact-fixer.py or a similar tool.
*
* Affected nodes:
* - cc.Sprite / cc.SpriteBatchNode and subclasses: cc.LabelBMFont, cc.TMXTiledMap
* - cc.LabelAtlas
* - cc.QuadParticleSystem
* - cc.TileMap
*
* To enabled set it to 1. Disabled by default.
*
* Senconds between FPS updates.
* 0.5 seconds, means that the FPS number will be updated every 0.5 seconds.
* Having a bigger number means a more reliable FPS
*
* Default value: 0.1f
*
* If enabled, the cc.Node objects (cc.Sprite, cc.Label,etc) will be able to render in subpixels.
* If disabled, integer pixels will be used.
*
* To enable set it to 1. Enabled by default.
*
* If enabled, the cc.Sprite objects rendered with cc.SpriteBatchNode will be able to render in subpixels.
* If disabled, integer pixels will be used.
*
* To enable set it to 1. Enabled by default.
*
* If most of your imamges have pre-multiplied alpha, set it to 1 (if you are going to use .PNG/.JPG file images).
* Only set to 0 if ALL your images by-pass Apple UIImage loading system (eg: if you use libpng or PVR images)
*
* To enable set it to a value different than 0. Enabled by default.
*
* Use GL_TRIANGLE_STRIP instead of GL_TRIANGLES when rendering the texture atlas.
* It seems it is the recommend way, but it is much slower, so, enable it at your own risk
*
* To enable set it to a value different than 0. Disabled by default.
*
* By default, cc.TextureAtlas (used by many cocos2d classes) will use VAO (Vertex Array Objects).
* Apple recommends its usage but they might consume a lot of memory, specially if you use many of them.
* So for certain cases, where you might need hundreds of VAO objects, it might be a good idea to disable it.
*
* To disable it set it to 0. disable by default.(Not Supported on WebGL)
*
* If enabled, NPOT textures will be used where available. Only 3rd gen (and newer) devices support NPOT textures.
* NPOT textures have the following limitations:
* - They can't have mipmaps
* - They only accept GL_CLAMP_TO_EDGE in GL_TEXTURE_WRAP_{S,T}
*
* To enable set it to a value different than 0. Disabled by default.
*
* This value governs only the PNG, GIF, BMP, images.
* This value DOES NOT govern the PVR (PVR.GZ, PVR.CCZ) files. If NPOT PVR is loaded, then it will create an NPOT texture ignoring this value.
*
* If enabled, cocos2d supports retina display.
* For performance reasons, it's recommended disable it in games without retina display support, like iPad only games.
*
* To enable set it to 1. Use 0 to disable it. Enabled by default.
*
* This value governs only the PNG, GIF, BMP, images.
* This value DOES NOT govern the PVR (PVR.GZ, PVR.CCZ) files. If NPOT PVR is loaded, then it will create an NPOT texture ignoring this value.
*
* It's the suffix that will be appended to the files in order to load "retina display" images.
*
* On an iPhone4 with Retina Display support enabled, the file @"sprite-hd.png" will be loaded instead of @"sprite.png".
* If the file doesn't exist it will use the non-retina display image.
*
* Platforms: Only used on Retina Display devices like iPhone 4.
*
* If enabled, it will use LA88 (Luminance Alpha 16-bit textures) for CCLabelTTF objects.
* If it is disabled, it will use A8 (Alpha 8-bit textures).
* LA88 textures are 6% faster than A8 textures, but they will consume 2x memory.
*
* This feature is enabled by default.
*
* If enabled, all subclasses of cc.Sprite will draw a bounding box
* Useful for debugging purposes only. It is recommened to leave it disabled.
*
* To enable set it to a value different than 0. Disabled by default:
* 0 -- disabled
* 1 -- draw bounding box
* 2 -- draw texture box
*
* If enabled, all subclasses of cc.Sprite that are rendered using an cc.SpriteBatchNode draw a bounding box.
* Useful for debugging purposes only. It is recommened to leave it disabled.
*
* To enable set it to a value different than 0. Disabled by default.
*
* If enabled, all subclasses of cc.LabelBMFont will draw a bounding box
* Useful for debugging purposes only. It is recommened to leave it disabled.
*
* To enable set it to a value different than 0. Disabled by default.
*
* If enabled, all subclasses of cc.LabeltAtlas will draw a bounding box
* Useful for debugging purposes only. It is recommened to leave it disabled.
*
* To enable set it to a value different than 0. Disabled by default.
*
* If enabled, actions that alter the position property (eg: CCMoveBy, CCJumpBy, CCBezierBy, etc..) will be stacked.
* If you run 2 or more 'position' actions at the same time on a node, then end position will be the sum of all the positions.
* If disabled, only the last run action will take effect.
*
* If enabled, cocos2d will maintain an OpenGL state cache internally to avoid unnecessary switches.
* In order to use them, you have to use the following functions, insead of the the GL ones:
* - ccGLUseProgram() instead of glUseProgram()
* - ccGLDeleteProgram() instead of glDeleteProgram()
* - ccGLBlendFunc() instead of glBlendFunc()
*
* If this functionality is disabled, then ccGLUseProgram(), ccGLDeleteProgram(), ccGLBlendFunc() will call the GL ones, without using the cache.
* It is recommened to enable whenever possible to improve speed.
* If you are migrating your code from GL ES 1.1, then keep it disabled. Once all your code works as expected, turn it on.
