I was looking for some hit detection stuff for my object modeller
project[1] last night, and I'd kind of misread what 'containsPoint'
should do. I was looking for something that would detect whether a
point was _on_ a path, and it appears that containsPoint detects
points _bounded by_ a path. The docs are a little unclear on this
matter, I think, but I'll let that pass.
I was also looking for a hitPath (or hitCurveSegment really) method,
rather then containsPoint - so I also wrote a method of my own to do
that. Performance is immensly improved over using Apple's method - not
surprisingly, since mine is more specialized.
I share your opinion about the GnuStep method probably being buggy.

Damn. I just wrote my own (which doesn't deal with curve segments yet,
cause I don't need 'em) and posted it onto cocoadev. Could bear some
optimisation, but it works. SampleCode, HitDetection for them as what
care.
