For anyone considering writing an "OpenGL client":

It should not be a separate client, but a different backend for the 
drawing code.  Ideally the drawing system will be modular, with 
different drawing algorithms being used interchangably in all clients 
that support them.  The current two algorithms are iso and non-iso; they 
share most of their code (you could argue they're just variants of the 
same algorithm).
Unfortunately the drawing code isn't very modular; it is currently split 
between tilespec.c, mapview_common.c, and gui-xxx/mapview.c.
