Thanks for the suggestion.

I'm quite open to this idea. Internally cairo_surface_t already has a
reference count, so we can expose a function to increment that. The
cairo_t object doesn't need one internally, but I'm willing to concede
the addition of the couple of lines of code in order to help the
layers above.

So the two new API calls would be:

	cairo_reference (cairo_t *cr);

	cairo_surface_reference (cairo_surface_t *surface);

Any objections?
