So how exact is that clip region? Does it contain every pixel touched by
the clip? Or just those above a certain threshold? Or does it only do a
rough approximation of the clip (like cairo_clip_extents does)?

I think that's not necessary. All the use cases I've seen so far seem to
indicate you don't need it and get by fine with
cairo_region_get_rectangle(). But that's just the
lets-keep-the-API-small part in me speaking, so I certainly don't object
an API like that on principle.
