None of the Cairo functions that accept a pointer to cairo_t return
cairo_status_t. Most are void, although a few of the cairo_current
functions do return values. Instead, the status is always saved within
the cairo_t itself.

So there would be no problem with using the return value to indicate
intersection here.
