Description

Computes a smaller, non-power of two texture dimension for storing the bone matrices. It's a small memory savings in more common cases but why not. There shouldn't be any reason to require a PoT texture here since mipmaps aren't used:

bone count old size new size
17 16 12
65 32 20
257 64 36
1025 128 68
