+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.
