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