Hello,

I did not know these bindings, but there are too lowlevel for what I
want when I teach (only one type for GLenum).

The lowlevel bindings of gles use polymorphic variant, so reading the
mli, you know what is allowed for a given GL function.

Moreover, the highlevel bindings provide the necessary functions to
really program. For instance, the Matrix module provide a function to
compute the NormalMatrix from the ModelView matrix. I know it is not
hard to inverse/transpose and extract a sub 3x3 matrice from a given
matrice, idem for an equivalent to the lookat GLU matrix ... But it is
better if this is already done.

The idea would be to have (we are not there yet) Highlevel binding
that can not trigger GLerror ... with little impact on performance.

Cheers,
Christophe
