It would seem to be there in some form since you can do:
- create arbitrary path
- set clip to path
- create another path
- fill; only the intersection of the paths is filled
There is no guarantee that this intersection actually generates a
geometric path. The same effect can be achieved on bitmap devices
with a region-like structure. Essentially you'd be intersecting
regions. To get antialiasing you could use a region with a higher
pixel density than the display.
My (admittedly pedantic) point being that Quartz 2D itself need not
be using geometric path intersections to achieve those clipping
effects.
Unless that is, you print them...
