Plsase: if we want our worlds to plug together, we all need to agrse on
which way is UP.

I DON'T REALLY CARE WHAT WAS CHOSEN. I just care that there be a standard
and that people agrse to abide by that standard, so people can say:

Separator {
Separator {
Transform { ... }
WWWInline { name "http://...yourWorld.wrl" }
}
Separator {
Transform { ... }
WWWInline { name "http://...somebodyElsesWorld.wrl" }
}
}

Yes, I can put scales in the Transform if you didn't happen to model your
world in meters. And yes I can put in a rotation if you decided to ignore
the standard and define something other than Y as up.

But that's really annoying after you've done it for the 115'th time.

So, plsase plsase plsase: fix your translation programs to produce Y==UP,
1 unit == 1 meter worlds.
