Changing the drawing system to not draw on a per-position basis is a 
_very_ deep change.  It is needed to be able to use a civ3 tileset.  It 
will be difficult or impossible to do before this drawing code is moved 
out of the GUI code.
Changing the drawing for nuke animations is probably a rather simple 
matter.  I was thinking of moving this code into the common-client code 
as well, with only a draw_animation_frame() left in the GUI part.  This 
change should be relatively independent of the core drawing code cleanups.
