21  * NOTES
22  *
23  * WINE currently implements a very basic set of the DirectDraw functionality
24  * in graphics/ddraw.c. This implementation uses either the XFree86-DGA extension 
25  * to get very fast access to the graphics card framebuffer and doublebuffering
26  * features or Xlib, which is slower.
27  * The implementation using XFree86-DGA is as fast as the MS equivalent for the
28  * stuff that is implemented.
29  *
30  * Several applications already work, see below.
31  * Problems of the implementation using XFree86-DGA:
32  *
33  *      - XFree86 cannot switch depth on the fly.
34  *        This is a problem with X and unavoidable.
35  *        Current solution is to pop up a MessageBox with an error for 
36  *        mismatched parameters and advice the user to restart the X server
37  *        with the specified depth.
38  *      - The rest of the functionality that has to be implemented will have
39  *        to be done in software and will be very slow.
40  *      - This requires WINE to be run as root user so XF86DGA can mmap the
41  *        framebuffer into the addressspace of the process.
42  *      - Blocks all other X windowed applications.
43  *
44  * This file contains all the interface functions that are shared between
45  * all interfaces. Or better, it is a "common stub" library for the
46  * IDirectDraw* objects
