/** @def CC_ENABLE_GL_STATE_CACHE
If enabled, cocos2d will maintain（维持） an OpenGL state cache internally（内部的） to avoid unnecessary（不必要的；多余的） switches（开关）.
In order to use them, you have to use the following functions, instead 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 recommended to enable whenever（不管何时） 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.
Default value: Enabled by default

/** @def CC_FIX_ARTIFACTS_BY_STRECHING_TEXEL
If enabled, the texture coordinates will be calculated by using this formula（公式）:

- texCoord.right = texCoord.left + (rect.size.width*2-2)/(texture.wide*2);
The same for bottom and top.
This formula prevents（预防） 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
