commit 299697dc2324f79de5eedabc6b0b108df775017d
Author: Carlos Garnacho <carlosg gnome org>
Date: Fri Oct 22 10:38:21 2010 +0200
GtkStyleSet: Register the border-style and border-color properties
This is also implemented in the theming engine, although the default
CSS should be using it in order to theme buttons, troughs, sliders
and such.
