Actually, the libtiff wrapper is supposed to implement the Tiff class
which exists in Matlab and is missing in Octave.  So yeah, Matlab
compatibility is required.  Having imread/imwrite/imfinfo make use
that Tiff class is something to do after.

This whole having multiple __dunder__ functions which are then called
from almost single line m files seems a bit silly.  I think it would
be cleaner to do it all in C++.  Is there a way to add a class to
Octave from an oct file only?
