				File Summary: FExampleOverlap.cpp

   Creates a one frame movie with containing a single defineShape data tag block, which 
   has two squares:
   
	1) blue one over red one, both have a standard 1 pixel wide, black edge.
	2) but the display is always red over blue, independent of drawing order.
