           Summary: [librsvg] misrendering of aisleriot card theme

           Product: cairo
           Version: 1.9.1

Using librsvg trunk
[http://svn.gnome.org/svn/gnome-games-extra-data/trunk/cards/bellot.svg] and
cairo git master,
http://svn.gnome.org/svn/gnome-games-extra-data/trunk/cards/bellot.svg
misrenders the diamond cards (obvious in the screenshot at
http://www.gnome.org/~chpe/images/cairo-bellot-svg-bug.png ). 
It works with cairo 1.8.0.

    [cairo-spans] Hook up filling paths with spans to cairo-surface-fallback.c.

    This speeds up the mask generation step in cairo_fill() for the image
    surface by up to 10x in especially favourable cases.

    image-rgba                              twin-800 7757.80 0.20% -> 749.41
0.29%: 10.36x speedup
    image-rgba spiral-diag-pixalign-nonzero-fill-512   15.16 0.44% ->   3.45
8.80%:  5.54x speedup

    More typical simple non-rectilinear geometries are sped up by 30-50%.
    This patch does not affect any stroking operations or any fill
    operations of pixel aligned rectilinear geometries; those are still
    rendered using trapezoids.
