Thomas Gellekum 040395f4dd Rewrite video emulation. Features: 
- slightly more accurate VGA hardware emulation;
- more int 10 functions, especially wrt to palette handling;
- first shot at graphics support;
- mode switching.

Bugs:

- graphics too slow;
- only 16 color modes work for now;
- works only under X, and only with 16 bit TrueColor visuals;
- far from being genuinely useful (I can play an old EGA game now, though
  (mahjongg.exe)).

Also, the code has been cleaned up a bit (more to come in a separate commit).
