[mutter/wip/cairo: 12/14] theme: Remove dead code

[Jasper St. Pierre <jstpierre src gnome org>]

commit a7d3a94433bd717db9956183f0b1c25479a1ed62

    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.
