- Add a few more hardware internal formats that are supported. Some remaining

  ones require custom texstore, so they aren't done yet.
- Add YCBCR support commented out, since the yuvsquare test didn't work with
  just the bits I've added.
- Add the no-compression GL_ARB_texture_compression support.
- Add the driconf texture depth option and try to respect it.
