These 16 functions (1bpp, 2bpp, 4bpp, 8bpp @ 1x. 2x with flags and
without flags) are all *very* similar and look like

Are you planning on using 2x

Remember that I fought long and hard to get ArcEm to run at ARM2 speeds on
an Iyonix, so I don't really want us to start doing things that will harm

It looks like the other ports have something like it, so are there any
pointers for where to start hacking on it? Presumably, the scaling
