//
//				OutputMemory	Supplied memory for storage of resulting compress data.
// 								
//				nWidth			
//				nHeight			Texture dimensions: Power of 2 square textures currently

//                              16x8 through 2048x2048 for 2 bpp cases.
//				bMipMap			Generate all mipmap levels. Recommended for rendering speed & 
//								quality
//				bAlphaOn		Is alpha data supplied? If not, assumed Alpha == 0xFF
//
//				bAssumeTiles	The texture wrap around the edges.
