OpenSceneGraph/applications/osgconv/osgconv.cpp
Robert Osfield 8b37ff25e7 From Laurens Voerman, "I crashed osgconv while compressing textures: 
osgconv --compressed-dxt1 cow.osg cow.ive

due to different handling of the extentions in osg 3.4 and up.

attached is a zip with the files:

OpenSceneGraph\applications\osgconv\osgconv.cpp



This file is valid for svn branch and stable3.4."
