…izer The current -[CCSprite initWithTexture:rect:] explicitly passes a 'NO' value for rotation to -[CCSprite setTextureRect:rotated:untrimmedSize:]. This change adds the rotated BOOL param as part the initializer, allowing the initialization of sprites with a rotated rect.
OpenGLES 2.0 does not support glAlphaTest or glAlphaFunc. This change set adds a simple fragment shader to the default set of cocos2d shaders that performs the equivalent of a glAlphaTest with by comparing the incoming alpha value with a specified uniform float, using the equivalent of a (greater-than-or-equal-to) '>=' comparison. This produces the same results as: glAlphaFunc(GL_GREATER, <value>) glEnable(GL_ALPHA_TEST) However, due to the use of shaders, the configuration is slightly different, since for cocos2d, use of the alpha test shader must specified on a per-drawing-node basis.
…ite frames. This allows a dictionary or plist of sprite frames to be associated with the specified texture or a texture file. This was possible in cocos2d 1.x, but is not present in the current 2.x branch.
…xtureCache. CCTextureCache is already a singleton, so these queues will only be created once. Declaring them as ivars allows them to be accessed in categories of CCTextureCache that extend/modify loading behavior.
This change adds the optional 'rotated' param to specify a rotated rect when creating a sprite with a batch node.

Hi Riq,
We're in the process of porting an app to the gles20 branch. In the process, I added a few pieces of missing functionality (i.e. alpha test support), and other methods that made the process easier.
