/* DirectDraw using DGA
*
* Copyright 1997-2000 Marcus Meissner
* Copyright 1998-2000 Lionel Ulmer (most of Direct3D stuff)
*/
/* XF86DGA:
* When DirectVideo mode is enabled you can no longer use 'normal' X
* applications nor can you switch to a virtual console. Also, enabling
* only works, if you have switched to the screen where the application
* is running.
* Some ways to debug this stuff are:
* - A terminal connected to the serial port. Can be bought used for cheap.
* (This is the method I am using.)
* - Another machine connected over some kind of network.
