I want to determine whether a line between two CGPoints in a view
intersects with a given CGRect. There's nothing in the CGGeometry
reference that does this specifically, and I don't yet see how to use
the functions that are there to figure this out.
Before I dust off my Euclid (a rare first edition), has anyone got a
quick solution? It seems the sort of thing that would be handy in many
situations.
