Detailed Description

CCTexturePVR.

Object that loads PVR images.

Supported PVR formats:

• RGBA8888
• BGRA8888
• RGBA4444
• RGBA5551
• RGB565
• A8
• I8
• AI88
• PVRTC 4BPP
• PVRTC 2BPP

Limitations: Pre-generated mipmaps, such as PVR textures with mipmap levels embedded in file, are only supported if all individual sprites are of square size. To use mipmaps with non-square textures, instead call CCTexture2D::generateMipmap on the sheet texture itself (and to save space, save the PVR sprite sheet without mip maps included).
