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).
