* \name Basic hardware formats
*
* The mesa format name specification is as follows:
*
* There shall be 3 naming format base types: those for component array
* formats (type A); those for compressed formats (type C); and those for
* packed component formats (type P). With type A formats, color component
* order does not change with endianess. Each format name shall begin with
* MESA_FORMAT_, followed by a component label (from the Component Label
* list below) for each component in the order that the component(s) occur
* in the format, except for non-linear color formats where the first
* letter shall be 'S'. For type P formats, each component label is
* followed by the number of bits that represent it in the fundamental
* data type used by the format.
*
* Following the listing of the component labels shall be an underscore; a
* compression type followed by an underscore for Type C formats only; a
* storage type from the list below; and a bit with for type A formats,
* which is the bit width for each array element.
*
*
* ---------- Format Base Type A: Array ----------
* MESA_FORMAT_[component list]_[storage type][array element bit width]
*
* examples:
* MESA_FORMAT_A_SNORM8 - uchar[i] = A
* MESA_FORMAT_RGBA_16 - ushort[i * 4 + 0] = R, ushort[i * 4 + 1] = G,
* ushort[i * 4 + 2] = B, ushort[i * 4 + 3] = A
* MESA_FORMAT_Z_UNORM32 - float[i] = Z
*
*
*
* ---------- Format Base Type C: Compressed ----------
* MESA_FORMAT_[component list*][_*][compression type][storage type*]
* * where required
*
* examples:
* MESA_FORMAT_RGB_ETC1
* MESA_FORMAT_RGBA_ETC2
* MESA_FORMAT_LATC1_UNORM
* MESA_FORMAT_RGBA_FXT1
*
*
*
* ---------- Format Base Type P: Packed ----------
* MESA_FORMAT_[[component list,bit width][storage type*][_]][_][storage type**]
* * when type differs between component
* ** when type applies to all components
*
* examples: msb <------ TEXEL BITS -----------> lsb
* MESA_FORMAT_A8B8G8R8_UNORM, RRRR RRRR GGGG GGGG BBBB BBBB AAAA AAAA
* MESA_FORMAT_R5G6B5_UNORM BBBB BGGG GGGR RRRR
* MESA_FORMAT_B4G4R4X4_UNORM XXXX RRRR GGGG BBBB
* MESA_FORMAT_Z32_FLOAT_S8X24_UINT
* MESA_FORMAT_R10G10B10A2_UINT
* MESA_FORMAT_R9G9B9E5_FLOAT
*
*
*
* ---------- Component Labels: ----------
* A - Alpha
* B - Blue
* DU - Delta U
* DV - Delta V
* E - Shared Exponent
* G - Green
* I - Intensity
* L - Luminance
* R - Red
* S - Stencil (when not followed by RGB or RGBA)
* U - Chrominance
* V - Chrominance
* Y - Luma
* X - Packing bits
* Z - Depth
*
*
*
* ---------- Type C Compression Types: ----------
* DXT1 - Color component labels shall be given
* DXT3 - Color component labels shall be given
* DXT5 - Color component labels shall be given
* ETC1 - No other information required
* ETC2 - No other information required
* FXT1 - Color component labels shall be given
* FXT3 - Color component labels shall be given
* LATC1 - Fundamental data type shall be given
* LATC2 - Fundamental data type shall be given
* RGTC1 - Color component labels and data type shall be given
* RGTC2 - Color component labels and data type shall be given
*
*
*
* ---------- Storage Types: ----------
* FLOAT
* SINT
* UINT
* SNORM
* UNORM
* SRGB - RGB components, or L are UNORMs in sRGB color space.
* Alpha, if present is linear.
