From Martin Aumueller, "in order to remove a dependency on Coin3D (which is GPLed) and make it work

with SGI's OpenInventor, I had to change
OpenSceneGraph/src/osgPlugins/Inventor, as SoVRMLImageTexture is not avaible
in SGI's Inventor. "

From Robert Osfield, tweaked the above so that it uses Coin headers to switch on coin features:
