This should be a quick one. I can't seem to get this simple one.

as the title indicates, I would for this framequad to have perfectly closed

corners when the gllinewidth is @ max (which seems to be 10)

Basically I seem to need to have the top/bottom OR Left/Right lines draw a little longer.

Thanks in advance for any help on this :-)
