You can have Quartz intersect a path with the current clipping path, but the result replaces the current clipping path and is not returned for use. A cursory look through the docs found no way to obtain the current context's clipping path.
If the context's clipping path could be obtained, then this would be a hacky way of getting intersected paths - as long as you saved state beforehand, and restored it afterward, so that the hack didn't change the clipping path used for actual drawing.
Assuming this could even be done, saving and restoring state might make it undesirable for heavy use.
