tip - group margins

[Rodney Tamblyn]

I've been making a little image editing stack and ran across something 
interesting.

I was using a group to display a crop rectangle, and kept finding that 
although I set the rect of the group to the rect of the image (when 
first showing the crop box), when I displayed the rects of both objects 
they were different by 4 pixels (even though appearing to be identical 
on screen).

The key is to remember that objects like groups have margins which are 
automatically applied, therefore in my situation I needed to do the 
following:

set the margins of group "crop" to 0
