We ignore the bottom 4 bits of the X resolution, so we should
round X resolutions up to the nearest multiple of 16.

We were supporting 24bpp. However, the pixel organisation in
memory was 0RGB, so it was 24bpp in 32bit words. This means
we're actually supporting 32bpp and not 24bpp.
Also, add a check to ensure that we don't exceed the available
framebuffer when changing display resolutions.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
