Rename gussianMap to gaussianMap (who the heck is gus?) Allow for other
names for the root pixmap Handle non-zero border widths better (need
Composite change to display them though). Add MONITOR_UPDATE mode that
eliminates double buffering and blanks the screen to make sequence of
update operations visible. Leave damage object around to catch map
damage right. Add CirculateNotify support.
