The problem is that there are (at least) three VTKWriter variants: VTKWriter,
VTKSequenceWriter, and SubSamplingVTKWriter.  When we construct a
VTKFunctionAdapter in PDELab, it is not clear which VTKWriter variant it is
going to be used with.  Extracting the base class as VTKWriter::Function and
then using it with a SubsamplingVTKWriter is kind of quite messy: you have to
know exactly which VTKWriter is the base to a particular SubSamplingVTKWriter,
and that should actually be an implementation detail.

Moreover, Dune::VTKFunction<Grid> is listed in the Doxygen documentation
module for the VTKWriter, so it looks quiet official.

OK, I'll look for a good example.  But don't expect it today, I'm kind of busy
with dune-geometry right now.

@Adrian: You noticed this first, do you maybe have a good example?

Bye,
Jö.
