FIX_ARTIFACTS_BY_STRECHING_TEXEL

If enabled, the texture coordinates will be calculated by using this formula:
- texCoord.left = (rect.x*2+1) / (texture.wide*2);
- texCoord.right = texCoord.left + (rect.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 expand the texture's border with the same color by 1 pixel

Affected nodes:
- _ccsg.Sprite

Disabled by default. To enabled set it to 1.
To modify it, in Web engine please refer to CCMacro.js, in JSB please refer to CCConfig.h

OPTIMIZE_BLEND_FUNC_FOR_PREMULTIPLIED_ALPHA

If most of your images 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)

TEXTURE_NPOT_SUPPORT

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.
To modify it, in Web engine please refer to CCMacro.js, in JSB please refer to CCConfig.h

废弃(Deprecated) This value will be removed in 1.1 and NPOT textures will be loaded by default if the device supports it.
USE_LA88_LABELS

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.

ENABLE_STACKABLE_ACTIONS

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.

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, instead of the the GL ones:
- cc.gl.useProgram() instead of glUseProgram()
- cc.gl.deleteProgram() instead of glDeleteProgram()
- cc.gl.blendFunc() instead of glBlendFunc()

If this functionality is disabled, then cc.gl.useProgram(), cc.gl.deleteProgram(), cc.gl.blendFunc() will call the GL ones, without using the cache.
It is recommend 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.

TOUCH_TIMEOUT

用于甄别一个触点对象是否已经失效,并且可以被移除的延时时长 添加这个时长的原因是 X5 内核在微信浏览器中出现的一个 bug。 在这个环境下,如果用户将一个触点从底向上移出页面区域,将不会触发任何 touch cancel 或 touch end 事件,而这个触点会被永远当作停留在页面上的有效触点。 重复这样操作几次之后,屏幕上的触点数量将达到我们的事件系统所支持的最高触点数量,之后所有的触摸事件都将被忽略。 所以这个新的机制可以在触点在一定时间内没有任何更新的情况下视为失效触点并从事件系统中移除。 当然,这也可能移除一个真实的触点,如果用户的触点真的在一定时间段内完全没有移动(这在当前手机屏幕的灵敏度下会很难)。 你可以修改这个值来获得你需要的效果,默认值是 5000 毫秒。
