I would strongly recommend using an Ada-type naming convention.  Even 
the  OpenGL definition recognizes that the "C naming convention" is only 
due to C's limitations and recommends using a "real" naming with real 
languages (see the Red Book - ok, the "real languages" part is my wording).

Someone trying to use a tutorial ought to be able to understand the 
change from "glVertex3i(x,y,z)" to "GL.Vertex(x, y, z : Int)".

(Of course there is a problem with overloading multiple integral and 
real versions - calls with only literal arguments need some kind of 
kludge.  I've never found a good solution.)
