Yes, these are the 4 points...

I think you should add:

((SVGLocatable)shape).getBBox();

((SVGLocatable)shape).getScreenCTM();

Add print statements for bPt1-4 to the above, then run this code before
the move and after, the result should be the screen pixel coords of
the shape before and after the move.
