[Pkg-fonts-devel] Bug#524310: fontforge: Seems to be caused by X misreporting screen size

[Deekoo L.]

Package: fontforge
Version: 0.0.20080429-1
Followup-For: Bug #524310


The fontforge bug was actually a manifestation of an xserver bug 
(reported as #528221) - since WidthMMOfScreen was returning 1, fontforge
was rendering everything at 1600 pixels per millimeter.  A workaround patch
against fontforge 20090408 (that may also work on the version in Lenny) is
enclosed, though fixing X to report reasonable screen sizes is probably 
better.
