* $Log: XWindow.c,v $
* Revision 1.4 2000/03/25 05:50:43 reinelt
*
* memory leak in Raster_flush closed
* driver family logic changed
*
* Revision 1.3 2000/03/24 11:36:56 reinelt
*
* new syntax for raster configuration
* changed XRES and YRES to be configurable
* PPM driver works nice
*
* Revision 1.2 2000/03/23 07:24:48 reinelt
*
* PPM driver up and running (but slow!)
*
* Revision 1.1 2000/03/22 15:36:21 reinelt
*
* added '-l' switch (list drivers)
* generic pixmap driver added
* X11 Framework done
