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 *
