Well, it seems the old XBoard code did not need this, because it was
extremely clever in finding out what covered what, and only copied
the visible parts. But this code has been disabled now, and the GTK
code for dragging the piece is of the more straightforward 'background
first' type.

The dragging is only a minor cosmetic problem, though. The problem
in animateMoving is far worse; there the stuff that is supposed to be
drawn gets really overwritten by the background (presumably through
undesired calls to DrawPosition in the expose-event handler), so that
it is permanently erased.
