osg::ref_ptr<osg::Node> ReaderWriterVRML2::convertFromVRML(openvrml::node *obj)
The fixes are:
* Added the source's parent directory as search directory for image files.
* The material properties are now set in the stateset of the Geode rather than the Geometry. This will allow geometries to be reused with different material properties in future updates.
NB: I planned for a caching scheme in which multiple occurences of the same primitive (e.g., Cylinders with radius 0.8 and height 1.2), would use the same Geometry object. Unfortunately, my planning moved me to other areas, but I might still finish the caching scheme in a quiet hour. For the time being I decided it would be a good thing to already submit my current changes.
