One way to implement such a scaling system would be to use Xv, rather than
mode-setting.  The 2D engine does support scaling with Xv, so a 400x300 3D
area could be scaled up to fill the whole screen.

Unfortunately, neither SDL nor Mesa seems to have built-in support for
using Xv to scale output, so a substantial amount of work is required in
software.
