When regions of the source rectangle are obscured and have not been
retained in backing store 
or regions outside the boundaries of the source drawable are specified
and the destination is a window with a background other than
.S None ,
then all corresponding destination regions that are either
visible or are retained in backing store
are tiled with that background
with plane-mask of all ones and the
.S GXcopy 
function.
>>STRATEGY
For all visuals
	make src window and draw into it (background of 0)
	make dest window with background of 1 and draw into it
	copy region that extends off the edge of the source drawable
	verify that it is not copied.
	verify that the background is tiled in parts corresponding to uncopied area.

When
