+<b>Silhouette edges don't fade out in movies</b><br>
+Tom Goddard<br>
+October 1, 2009<br>
+It is useful to fade in and out surfaces in movies by varying their transparency
+with the surftransparency command (e.g. "surft 100 #3 25" change surface #3 to
+100% transparent over 25 frames).  When showing silhouette edges the edges don't fade
+with the surface, making for an unsatisfactory fade out.  Could the edges be made to
+match the transparency of the surface?  I think that is not possible with the current
+stencil buffer algorithm.  Silhouette edges are very useful for giving depth to
+transparent surfaces, so it would be nice to be able to use them in movie fades.
