-// Ported to OSG by Tim Moore - Jun 2007

-// Heavily modified to be usable for the 2d Canvas by Thomas Geymayer - April 2012
-// Supports now multisampling/mipmapping, usage of the stencil buffer and placing
-// the texture in the scene by certain filter criteria
+// Moved to SimGear by Thomas Geymayer - October 2012
