[cairo] [PATCH] pdf: Quell warning comparing cairo_status_t and _cairo_int_status types

[Chris Wilson]

The goal here is to use cairo_int_status_t consistently for internal
error reporting, with the cast to cairo_status_t on the boundary (e.g.
when it gets reported via a public function, or set on an object). At
the boundary, we then check that the error is a legal public
cairo_status_t.

So I dropped this patch in favour of converting function returns to
cairo_int_status_t.
