[mutter/wip/cb2eb3: 11/55] theme: Remove dead code



commit a198ff415a8e11298c81fb1bed1432b4d242108e
Author: Jasper St. Pierre <jstpierre mecheye net>
Date:   Thu Mar 1 00:27:10 2012 -0500

    theme: Remove dead code
    
    While the comment claims that we may want to keep this around
    for optimization purposes, the operations are raw bitmap operations
    that would be cleaner done in cairo.
