From 9c311b3208f25ce70edf0fdbe0f440ecd8e0bda7 Mon Sep 17 00:00:00 2001
From: Paul Mackerras <paulus@samba.org>

Subject: gitk: Use named fonts instead of the font specification

This replaces the use of $mainfont, $textfont and $uifont with named
fonts called mainfont, textfont and uifont.  We also have variants
called mainfontbold and textfontbold.  This makes it much easier to
make sure font size changes are reflected everywhere they should be,
since configuring a named font automatically changes all the widgets
that are using that font.
