I just noticed that we have two tags for the same scenegraph library. Namely osg with 29 tags and openscenegraph with 48 tags. Often they are even used together. I can go ahead and retag them all openscenegraph since that seems to be the most popular.
Given that the library is often referred to as OSG (and all code resides in a similarly named namespace) could we go ahead and make them synonyms of each other? I fear that otherwise the tag might created again.
