Not an easy, user-level way.
For canvasitems having SVP-s (sorted vector paths) - most usual shapes
on aa canvas, you can always do art_svp_intersect and test, if result is
empty. You probably would also want to check their binding boxes
overlapping first :) But such API will be unportable and so should be
implemented inside item definitions.
