CCTexture2D class. This class allows to easily create OpenGL 2D textures from images, text or raw data. The created CCTexture2D object will always have power-of-two dimensions. Depending on how you create the CCTexture2D object, the actual image area of the texture might be smaller than the texture dimensions i.e. "contentSize" != (pixelsWide, pixelsHigh) and (maxS, maxT) != (1.0, 1.0). Be aware that the content of the generated textures will be upside-down!

| + (CCTexture2DPixelFormat) defaultAlphaPixelFormat |
returns the alpha pixel format
| - (void) drawAtPoint: | (CGPoint) | point |
draws a texture at a given point
| - (void) drawInRect: | (CGRect) | rect |
draws a texture inside a rect
| - (void) generateMipmap |
Generates mipmap images for the texture. It only works if the texture size is POT (power of 2).

| - (void) setAliasTexParameters |
sets alias texture parameters:
| - (void) setAntiAliasTexParameters |
sets antialias texture parameters:
| + (void) setDefaultAlphaPixelFormat: | (CCTexture2DPixelFormat) | format |
sets the default pixel format for UIImages that contains alpha channel. If the UIImage contains alpha channel, then the options are:
How does it work ?
| - (void) setTexParameters: | (ccTexParams *) | texParams |
sets the min filter, mag filter, wrap s and wrap t texture parameters. If the texture size is NPOT (non power of 2), then in can only use GL_CLAMP_TO_EDGE in GL_TEXTURE_WRAP_{S,T}.
