That's ridiculous.  You'd have to define it anyway before you could do 
multiple calls.  We should just look up the definition (in the gtk-2.x 
source code, most likely) and use that.  Other GUIs can either conform 
or end up with trivially different behavior.

Also if you rely on the implementation to be precise you run into a much 
bigger problem with border (dashed) lines.  Are we going to do the 
dashing ourselves?  Isn't this what graphics libraries are for?
