M Joonas Pihlaja 18634c3702 [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.
