I'm always afraid of "designed by committee"

http://en.wikipedia.org/wiki/Design_by_committee

pov SDL is not that orthodox (a little bit more of absolut orthodoxy
in its concept could really help the learning curve of beginners),
but I have always ponders that issue with backward compatibility.

If I was to change the parser and the data structure, I would limit
myself to make the same capability for finish than for normal and
pigment, and drop the texture. And change the model for color
(separating filtering pigment from ray-data, so as to be able to
process ray's color with a matrix [changing the wavelength when
hitting a surface, in any way you can thing of]) to an open-model
which could play Grey-only, RGBa, as well as discret spectrum (or
anything you can thing of).

(in french, have a look at the UML if you cannot read it...most
complex is on page 40.)
