Why is minor component displayed at left ?

[ggaliens]

Micheus ... Dan ... I think I'm seeing a potential weakness in OpenGL version vetting ...
Look at this testing I have done on command line ...

Code:

1> {2,1} < {3,1,2}.
true
2> {2,1} < {2,1,2}.
true
3> {2,1} < {2,0,2}.
true
4>

My thought would be to put in an "assertion" that both tuples are three tuples ... else toss in a fatal.
Anyways ... I'm going to try to PUSH an improved version for you guys to ponder.

Maybe something like this is better ...

Code:

minor_gl_version() ->
    Major = 2,
    Minor = 1,
    Req = {Major,Minor,0},
    case ets:lookup(wings_gl_ext, version) of
    [{_,{MajorCurrent,MinorCurrent,_}=VerTuple}] when VerTuple < Req ->
        fatal("Wings3D requires OpenGL ~p.~p or higher.\nYour available version ~p.~p",
          [Major,Minor,   MajorCurrent,MinorCurrent]);
    [{_,{_,_,_}=_VerTuple}]  ->  % assert that a 3 tuple is returned as expected
        ok;
    Unexpected ->
        fatal("Unexpected current OpenGL info : ~p", [ Unexpected ])
    end.
