 // Below we set the order for ARGB channels in registers. I suspect that, on
 // big endian machines, you can keep this the same and everything will work.
 // The in-memory order will be different, of course, but as long as everything
 // is reading memory as words rather than bytes, it will all work. However, if
 // you find that colours are messed up I thought that I would leave a helpful
 // locator for you. Also see the comments in
