It doesn't require a certain word size.
Windows prefers everything as BGR, while other OSes prefer RGB. Anything that is a multiple of 8 bits is subject to byte order rules (I have yet to see a 96 bit word CPU, either - but extended precision floating point is also subject to byte order).
but BGR and RGB isn't a byte-order issue, like the Intel/Motorola thing.
well, let me restate that: i'd be very surprised to learn that Microsoft went with BGR because the early Intel CPUs cared about the order of the bytes in certain 24-bit data structures.
