Still don't see what the problem is: you wanted LIBGL to control do world -
sure, go ahead. All I asked for is to not rub the middle finger in someone's
face just because they never came to personally tell you that's the way they
do things. Essentially I'm trying to find a compromise that works for everyone
yet you come with the "no one" and "ever" statements, which are a bit silly
IMHO, especially in the context of an open-source project.

I'm quite "enjoying" this bike-shedding. People just refuse that others may
have with different work flow than theirs. Well... I'm off this topic enjoy
your "world domination" plan :P
