[x3d-public] Isolating problems with HAnimHumanoid.java and X3DUOM, etc.

[John Carlson]

Lighthearted tech humor.

I understand that there’s a HAnimHumanoid.children field in the DOM.  I’m
not sure about the scenegraph though…how would you add to it?  Some kind of
multiplexing?  The mind boggles at the possibilities.  Also, what does
HAnimHumanoid.children field mean on input or output?  Oh, it’s hidden?
You mean in XML, not in X3D JSON.  I doubt if you’d like to see a
HAnimHumanoid.children field in VRML either.  Is the children field hidden
in VRML as well?

Yes, I’ve seen a children field instead of joints in JSON and VRML.  I
fixed those suckers.  Try getting that  VRML children field past
castle-model-viewer guards.

Believe me, I made a valiant attempt at smuggling the VRML children field
into castle.  The guards turned me back.  Maybe I could now that I had a
Pascal refresher.  I’m afraid my pull request would get hot oil poured all
over it.

I wouldn’t have even found setContainerFieldOverride if Don hadn’t said it
wasn’t in his code.  That’s the real beauty here, Don gave me the
workaround.  He’s a genius!  It took me like a week to realize it though.

Now, let’s do it the right way.  I’m guessing someone is already doing that!
