Detailed Description

CC3Texture2D is a cluster subclass of CCTexture2D.

CC3Texture2D provides more automated tracking of mipmaps and texture orienation. In particular, by instantiating a CC3Texture2D instead of the CCTexture2D superclass:

• The hasMipmap property will correctly indicate the presence of a mipmap in a texture loaded from a PVR file that already contains a mipmap, so that a subsequent invocation of generateMipmapIfNeeded will not overwrite this loaded mipmap, and that loaded mipmap can be used by the CC3Texture even if the shouldGenerateMipmaps is set to NO.
• The isFlippedVertically property is automatically set to NO when the instance was loaded from a PVR file, and set to YES otherwise.
• When an instance of CC3Texture2D is deallocated, it automatically sets the hasMipmap property to NO, and the isFlippedVertically to YES, before deallocation. This avoids potential confusion if the same texture name is reused by the GL engine for a CCTexture2D instance.

CC3Texture automatically causes an instance of CC3Texture2D to be instantiated by CCTextureCache when the CC3Texture is loaded from a file.

+ (BOOL) PVRImagesHavePremultipliedAlpha

This is a replication of the same class-side property of the CCTexture2D superclass.

If you change the value of the superclass property, you should also change the value of this property to match.

+ (void) PVRImagesHavePremultipliedAlpha:

(BOOL)

haveAlphaPremultiplied

This is a replication of the same class-side property of the CCTexture2D superclass.

If you change the value of the superclass property, you should also change the value of this property to match.
