Subject: [PATCH] From Brede Johansen, "Here's a small patch to
 BlendFunc::setFunction(source,destination) to make it consistent with the
 constructor and prevent the BlendFuncSeparate path being called.  This patch
 fixed the artifact with the osgpointsprite demo on ATI cards reported by Mike
 Weiblen."
