Sometime ago, we did talk about an API for clipping to a list of
device-pixel aligned rectangles. And for a while, we even had the API
stubs inside a comment within cairo.h.

Since then, Graydon Hoare has implemented code under cairo_clip that
automatically detects if the path consists of a device-pixel algined
rectangle, and if so, does the more efficient clipping.

Our hope is that with this support we won't need a separate API.

So, try giving his implementation a try, and see if it won't do what you
need.
