vertex

Helper function for obtaining coordinates of vertices in the shape.

void vertex(tSigned32 index, tSigned32& x, tSigned32& y) const;

	index		Index of the vertex for which to obtain coordinates.
	x		This will be set to the x coordinate of the vertex.
	y		This will be set to the y coordinate of the vertex.

The coordinates are relative to the shape origin.
Note that the order of vertices may differ from the order used when initially creating the shape.
