What do you think? Well, if you're already familiar with similar techniques from the framebuffer work (and it doesn't require you to wade through the TinyGL code) my suggestion would be to take a stab at the latter method first. If you find that doesn't work you can always fall back on the TinyGL code, but if it works the second method using only already-standard Qt methods would probably be easier, cleaner and simpler. That said, you are now very experienced in matters libdm/libfb + Qt - which approach would you prefer?
