While that sounds great -- I would settle for even a pseudo-code algorithm for
how to detect x y within a path. I have been searching and coming up blank
I have some ideas, but they involve sorting the xy of nodes and then stepping
around and testing bounds -- that's still fuzzy. I'm not well, so not
thinking clearly. Or converting a path to an image and testing for a colour.
Any hints ;)
