the display adapter code. When ready, the common gui code should handle it completely. The snapshot handler should set a flag 'snapshot_mode' and then it should force a display update. The graphics update code should be redirected to some code that 'draws' to a snapshot buffer. These first steps are done: - store some guest display settings in the gui code (text / graphics switch, x / y resolution and bpp) - split 8 bpp palette update code in a common and a specific part and store the palette values in the gui code
