Hey, quick question.
Is there functionality in The Render Engine (or maybe Sylvester?) to
find out if a point is inside a polygon?

PS: I'm using an algorithm i got from http://local.wasp.uwa.edu.au/~pbourke/geometry/insidepoly/
(the "Solution 3" to be specific - I test lines to find the matching
polygon). Thought I could replace it.

As it stands, there's nothing in the engine which determines point-to-
poly collision at the moment. I like the solution in #1, but it seems
intensive to perform that. Solution 3 looks good too. At some point,
I'll probably add a way, in Math2D, to do simple point-to-poly
collision.
