* In the algorithm above we're assuming that there are no vertices
* with a different bone weight setup at the same position. That wouldn't
* make sense, but it is not absolutely impossible. SkeletonMeshBuilder
* for example generates such input data if two skeleton points
* share the same position. Again this doesn't make sense but is
* reality for some model formats (MD5 for example uses these special
* nodes as attachment tags for its weapons).
*
* Then it is possible that a bone has no weights anymore .... as a quick
* workaround, we're just removing these bones. If they're animated,
* model geometry might be modified but at least there's no risk of a crash.
