commit 054dcbab2414e72d7c743214b7c56408fa4912dd
Author: Dima Kogan <address@hidden>
Commit: Jan D <address@hidden>
Try non-scaled xld fonts first, and scaled if that failed.
Fixes: debbugs:19117
* xfaces.c (realize_basic_faces): Don't set Qscalable_fonts_allowed to
t.
* font.c (font_score): Try to find a font without scaling first,
and only accept scalable fonts if we did not get a match.
