[Felix Riemann <friemann src gnome org>]

commit 871c2c2c97bc5bb3ada342c8ef27c310f4d22847
Author: Felix Riemann <friemann gnome org>

    Add simple printing support for SVGs
    
    Use librsvg to draw the SVGs to the cairo context during printing.
    Should improve print quality quite a bit. Fixes bug 518055.
