I was pondering how I'd be able to do non-square cursor
sizes without have a massive list of them in the SIZE_HINTS
blob.

So I came up with this idea of having a 2D bitmap in
there to indicate support for (mostly) POT non-square
sizes..

What does everyone think? Is this just getting too
complicated and should we just go with the original
"a list of suppored sizes" approach?
