    Don't we have that already? And even if not in my opinion it would
    be better to extend the existing GL units...

I don't want my three questions to get too side tracked, but I'll give 
you my reasoning on this point.

[...]
And instead have something like this in an OpenGL.pas unit:

var
  OpenGLManager: record
    Load: function: Boolean;
    GetProcAddress: function(ProcName: PAnsiChar): Pointer;
    ExtensionSupported: function(Extension: PAnsiChar): Boolean;
  end;

And allow other units to control how the OpenGL unit manages some 
functions. Essentially what this involves is a rewrite of the GL unit, 
which is what I am doing. See every one of the function Load_XXX: 
Boolean in GLext.pas.

Ok, so if you can do this in a way that SDL would not be needed if one 
doesn't want to use it and that using older OpenGL versions (e.g. 2.1) 
is supported I'd say: go for it :)

Regards,
Sven
