Ahh, just answered my question with "vtkMesaFreetypeTextMapper".

alot of the vtkMesa* objects state (in the documentation) that they
shouldn't be used as their parent objects will automatically determine
whether to use the Mesa or OpenGL version.  But it seems that I have
to explicitly specify creation of the Mesa widgets to get this to
work.  Am I doing something wrong, or is this by-design?
