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 
really. 

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 ;)
