The position handling is inherently broken on window-system frames too
because we translate negative values to positive ones after the window
manager has processed them.  But I'd like to handle values like (+ 10)
to make child frame dragging work so I'll implement that next.

I see.

Didn't you once mention that borders can be displayed more nicely?  I
obviously forgot how to do that.  In either case I'd like to resize
child frames by dragging their borders with the mouse.
