/** @def CC_ENABLE_GL_STATE_CACHE
 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.

 @since v2.0.0

/** @def CC_FIX_ARTIFACTS_BY_STRECHING_TEXEL
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:
- CCSprite / CCSpriteBatchNode and subclasses: CCLabelBMFont, CCTMXTiledMap
- CCLabelAtlas
- CCQuadParticleSystem
- CCTileMap

To enabled set it to 1. Disabled by default.
