-// Generate a directional light. This routines creates a
-// 'directional' light that can only be viewed from within 90 degrees
-// of the specified dir vector.
-
-// To accomplish this, he routine creates a triangle with the 1st
-// point coincident with the specified pt and the 2nd and 3rd points
-// extending upward. The 1st point is created with an 'alpha' value
-// of 1 while the 2nd and 3rd points are created with an 'alpha' of
-// 0.0.
-
-// If the triangle is drawn in glPolygonMode(GL_FRONT, GL_POINT) mode,
-// then two important things happen:
-
-// 1) Only the 3 vertex points are drawn, the 2nd two with an alpha of
-// 0 so actually only the desired point is rendered.
-
-// 2) since we are drawing a triangle, back face culling takes care of
-// eliminating this poing when the view angle relative to dir is
-// greater than 90 degrees.
-
-// The final piece of this puzzle is that if we now use environment
-// mapping on this point, via an appropriate texture we can then
-// control the intensity and color of the point based on the view
-// angle relative to 'dir' the optimal view direction of the light
-// (i.e. the direction the light is pointing.)
-
-// Yes this get's to be long and convoluted. If you can suggest a
-// simpler way, please do! :-)
