I can think of one reason why you must NOT #include glext.h from
within gl.h and that is that it could wreck existing programs
that conditionally compile extension code on the assumption
that they will be compiled and run on the same machine.
#ifdef GL_EXT_something_or_other
glSomethingOrOtherEXT () ;
#endif
Since glext.h defines ALL extensions for all machines, an
existing program that was only intended to run on the machine
it was compiled on would certainly break if glext.h were
rammed down it's throat by virtue of forced inclusion within
gl.h.
In effect, the meaning of GL_EXT_whatever tokens is
subtly changed in programs that include glext.h
Since that older program doesn't know about oglbase, it won't
include glext.h itself and should work just fine under the
proposed scheme where glext.h has to be explicitly included.
Dunno if this was the original reason - but we can't do
something that would break existing legal OpenGL programs,
so gl.h can't include glext.h (at least not unconditionally).
