GEMS

A number of geometrical functions to manipulate line segments and polygons are provided. Most of these are derived from articles presented in the "Graphic Gems" books.

In the following function names, a line is an infinite line going through 2 points while a segment is the portion of that line limited by the 2 points.

	GEMS_2D_Dist_Point_Segment	Return the distance between a point and a line segment on a 2D plane
	GEMS_3D_Dist_Point_Line	Return the distance between a point and a line in 3D space
	GEMS_2D_Intertsect_Segment_Segment	Return the intersection point between 2 line segments
	GEMS_2D_Intertsect_Line_Segment	Return the intersection point between a line segment and a line
	GEMS_2D_Tessellate	Create a 2D triangular tessellation of a "n" point polygon.
