[x3d-public] JSHumanoids repo—resize, reanimate your humanoids

[John Carlson]

You ask some difficult questions.  Ideally, one could specify a DEF node
and a list of Transforms to apply and a timestamp.

I’m guessing the Jaminate was along those lines, but more targeted at
creating Interpolators for turning on and off animations in a chains.

JSHumanoids is more like a one time animation, that takes XML input and
produces XML output.

I am thinking to de-emphasize Blender work, mainly because I suck at Python
and move back into Serializer and WinterAndSpring work.  A first goal would
be to have multiple IndexedFaceSets in a single humanoid.  I could start
work on replacing the Perl with Java-based JavaScript.

But I will need some data to work with, so JinLOA4.x3d looks like a good
start.
