[gnome-mines] Fixed rough image rendering. https://bugzilla.gnome.org/show_bug.cgi?id=730056

[Robert Roth <robertroth src gnome org>]

commit 9a887750fb286f8a55a0abf1f7072d9ff73bb032
Author: Robert Roth <robert roth off gmail com>
Date:   Wed Jul 2 00:48:32 2014 +0300

    Fixed rough image rendering.
    https://bugzilla.gnome.org/show_bug.cgi?id=730056
    
    Fixed rough image rendering by rescaling the SVG images on resize,
    instead of rescaling the pixbuf rendered from the SVG at the initial size.
