Volker Ruppert 4eae421272 Graphics snapshot feature re-implemented for the new graphics API 
- graphics_tile_info() split into a common and specific part
- store snapshot mode in structure bx_svga_tileinfo_t
- in snapshot mode, display adapters copy raw data to buffer
- rewrite of the trigger_timer() code to make it work in all cases
- added new class bx_nonvga_device_c to make forwarding refresh requests to the
  Voodoo adapter possible
