10 Bits Per Component
=====================
These formats store a 30-bit RGB triplet with an optional 2 bit alpha in four
bytes. They are named based on the order of the RGB components as seen in a
32-bit word, which is then stored in memory in little endian byte order
(unless otherwise noted by the presence of bit 31 in the 4CC value), and on the
number of bits for each component.
