gEDA-dev: Patch for gerbv and xinerama

[David Carr <dc-at-NOSPAMdcarr_dot_org>]

When I try to use gerbv 1.0.2 on my machine, it opens a window that is 
way bigger than my display.  The problem stems from the fact that I have 
an xinerama setup with a "screen size" of 2560x1280.

I've attached an old patch that I tweaked very slightly.  The original 
reference can be found here:
