_cairo_default_context_set_source_surface, when the surface passed in
is in error, returns a pattern->status without destroying the pattern
created which is not a static pattern nor part of a cairo owned set
of error patterns:
<a href="http://cgit.freedesktop.org/cairo/tree/src/cairo-default-context.c#n327">http://cgit.freedesktop.org/cairo/tree/src/cairo-default-context.c#n327</a>
Similarly cairo_get_source returns a leaked pattern when the context
passed in is in error:
<a href="http://cgit.freedesktop.org/cairo/tree/src/cairo.c#n833">http://cgit.freedesktop.org/cairo/tree/src/cairo.c#n833</a>
Valgrind reports this one running:
