I'm trying to use math to do all my aligning and things seem
to be "off". As far as I can tell it's because I don't know where
the thickness is being measured from. For example, if I have a
rectangle that is 2 pixels thick and I start it at X:0 and Y:0 then
I SHOULD be able to place the next object at X:2 and Y:0 and have
them butt right up next to each other. However it seems like maybe
the center of the stroke is being put at the 0,0 coordinate.
