Qtopia backend

Hey. Just a small teaser of things to come. This is the first snapshot
of SDL running within Qtopia. It’s a qvfb shot. I don’t have events
working yet, and display is not taking advantage (when possible) of
direct frame buffer access. But, it works. :slight_smile:

The algorithm for finding the longest path in a graph is NP-complete.
For you systems people, that means it’s real slow.
