Functionally there is no difference between altering a polygon's shape and 
the way I am moving it.

It doesn't have to get deleted and recreated each time, does it?  Wouldn't 
a single canvas coords subcommand be more efficient?

If you're just moving shapes, you might consider doing everything in edit 
mode with [cnv] objects-- it will be more efficient than data structures (which 
still get deleted when moving them in edit mode-- don't understand that at all) 
and you can track their position with the "get_pos" message.
