The F95 bindings as I had them were incomplete at two points;
- two-dimensional arrays like for plgriddata(), actually pointers to arrays
- functions that take other functions as arguments

The first can be solved at the C side.
The second can be solved by appropriate explicit interfaces (so that
the compiler can detect mismatches in the interfaces) and, if needed,
a small C wrapper.

That is something I want to realise the coming few days.
