Looking at the implementation of 'TextureObjectSet::takeOrGenerate', then a texture object from 'TextureObjectSet::_orphanedTextureObjects' might be reused and then 'glTexStorage2D' might be called multiple times on the same texture object, which would then result into GL_INVALID_OPERATION, because 'glTexStorage2D' should be only called once and afterwards the texture object is immutable in this regard. Is this right? Is there some kind of flag missing, if 'glTexStorage2D' has already been called?
