Structure that is used to manage texture information loaded in the texture memory. The following shows meanings of member "type" of each bit. Bits 31 to 24: Texture format type 0x01****** Twiddled texture 0x02****** Twiddled mipmap texture 0x03****** VQ texture 0x04****** VQ mipmap texture 0x05****** 4bpp palette texture 0x06****** 4bpp palette mipmap texture 0x07****** 8bpp palette texture 0x08****** 8bpp palette mipmap texture 0x09****** Rectangle texture 0x0B****** Stride texture 0x0D****** Twiddled Rectangle texture 0x10****** SmallVQ texture 0x11****** SmallVQ mipmap texture Bits 23 to 16: Texture color type 0x**00**** ARGB1555 0x**01**** RGB565 0x**02**** ARGB4444 0x**03**** YUV422 0x**04**** BUMP 0x**05**** RGB555 0x**06**** ARGB8888 or YUV420 Bits 0 to 15: Surface type 0x****0001 Frame buffer (This value is not used) 0x****0002 Non-small VQ texture 0x****0003 SmallVQ texture The following shows the value taken by member "BitDepth" which indicates color bit number of texture. 0x00000001 16-bit texture 0x00000002 24-bit texture 0x00000003 32-bit texture The following shows the value taken by member "PixelFormat" which indicates pixel format. 0x00000000 ARGB1555 0x08000000 RGB565 0x10000000 ARGB4444 0x18000000 YUV422 0x20000000 BUMP 0x28000000 PALETTIZED 4BPP 0x30000000 PALETTIZED 8BPP The following shows the value taken by member "fSurfaceFlags" which indicates surface flag. Bit 0 0 : No mipmap / 1 : Mipmap Bit 1 0 : Bit 1 is fixed to "0" Bit 2 0 : Rectangular texture / 1 : Twiddled texture Bit 3 0 : Non-VQ texture / 1 : VQ texture Bit 4 0 : Non-Stride texture / 1 : Stride texture Bit 5 0 : Non-Palette texture / 1 : Palette texture
