Worth (so to speak) also pointing out this bit:
As I talk about in the comment in the sample code, it may still be
beneficial to add some automatic snapping to cairo. It would simply
make it easier to achieve effects such as this---and in particular,
to achieve these effects regardless of what scaling the current
