From: Michael Adams <adams@flexibledoors.co.nz>
The CopyArea(W1,W2,x1,y1,w,h,x2,y2) function has the ability to copy a
rectangular area from one window to another, if W1 and W2 are different
windows. However, I can't find any information on how to name windows...
W1 and W2 are data values of type "window".
You'd do something like this:
W1 := WOpen(...)
W2 := WOpen(...)
...
CopyArea(W1,W2,...)
All graphics procedures accept window argument like W1 and W2,
but they're normally omitted when there's only one window open.
