/* inPoly()
Finds if a given point is within a polygon.

Based on Bob Stein's inpoly() function for C.
http://home.earthlink.net/~bobstein/inpoly/

Modified for JavaScript by Scott Andrew LePera.

Parameters:
poly: array containing x/y coordinate pairs that
  describe the vertices of the polygon. Format is
  indentical to that of HTML image maps, i.e. [x1,y1,x2,y2,...]
  
px: the x-coordinate of the target point.

py: the y-coordinate of the target point.

Return value:
true if the point is within the polygon, false if not.
