  I am planning to write some xcmds that would receive some coordinates and
a field and then draw either a bar or pie graph at that location.  But, whatever
I draw with the xcmd disappears apparently whenever there is a screen update.
I tried saving the screenBits, but whatever I draw still disappears.  Does 
Hypercard keep its own BitMap somewhere, or am I missing something?
