- Added C3D_TexCube structure for holding pointers to all 6 faces
- C3D_TexLoadImage accepts face number and mipmap level
- C3D_TexGenerateMipmap accepts face number
- Added functions (C3D_Tex*GetImagePtr) for accessing image data
- Now using GX to copy texture data to VRAM instead of failing
- Moved texunit setup code to texture.c
- Now supports multilevel data (LOD) used for mipmapping
- Basic mipmap generation (currently only for RGBA8 and RGB8 textures)
- Texture type can now be specified (TODO: support cube textures)
- Border color can also be specified now
- More flexibility in texture initialization parameters
