**** Minor Bug ****
Problem: Click on a node, and grab the right middle
resizing box. Jiggle it around and the left side of the
node will "walk" towards the right side. If you jiggle the
mouse up and down, nothing should happen, but the left
and right sides move towards each other. Note: Same
thing happens with all resizing boxes, noticeably more on
a corner box.
Possible Solution: This sounds like a rounding problem,
but not sure. The left side should be the point the node
is being drawn at. It should walk due to a resize.
