[x3d-public] X3DOM vs X_ITE? Browser bake-off, round 1

[John Carlson]

Oh, cool, I wasn’t aware one could set gamma correction with an Environment
element.  Good info!   Is this a cross-browser feature yet?

These are examples from the archives, I’ve just had them stashed for early
testing, probably in 2017.   I don’t know if any authors are in the files
yet.

I guess it’s time to separate myself from kinematics and get back to normal
stuff.
