Add preliminary support for patterns to rsvg-cairo, (doesn't do
2005-10-08 Carl Worth <cworth@cworth.org>
* rsvg-cairo-draw.c: (_set_source_rsvg_pattern): Add preliminary
support for patterns to rsvg-cairo, (doesn't do transformed
patterns yet).
* rsvg-cairo-draw.c:
(_set_source_rsvg_paint_server), (rsvg_cairo_render_path): Pass
the RsvgDrawingCtx down do the sub-functions since the pattern
drawing code needs it in order to call _rsvg_node_draw_children.
