NSView's cursor rect methods are handy, but they only work with rectangles. Likewise for the more general tracking rects. How does one change the cursor for an arbitrary part of a view? For example, can I specify that a closed NSBezierPath should have cursor X?

I guess I could approximate any shape with many small rectangles. Any idea if performance will degrade horribly with 100s or 1000s of cursor rects?

What I'd probably do is use a small number of rectangles to reasonably circumscribe the area I'm interested in and then use NZBezierPath>>containsPoint: once I've determined that the likelihood of a hit is worth the more expensive check.
