[cairo] [PATCH] Rely less on fast double-precision FPUs

[cu]

We only use image surface backend (frankly, in my opinion, that's where
Cairo shines - in fact so much so I wish there was a separate library
built from Cairo that had nothing but image surface, so that it could be
polished and optimized more, but I digress). From what little I've seen
inside Cairo, offsets are handled properly. This is very important for
certain types of drawing and it's one feature that makes Cairo valuable IMHO
