I agree that it should (in an ideal world) be 'char' - since
we are definitely passing characters - and (in theory) a
character might not fit into an unsigned byte.  The warning
is pretty ugly too.

HOWEVER...All the only other OpenGL function that deals with
characters refers to them as GLubyte (eg glGetString).

I think I vote for char* on balance.
