[x3d-public] What is a HAnimHumanoid?

[John Carlson]

Here are 2 version of JoeSkeletonSkinSiteSaluteWalk glTF, with animations
and without animations.  I will try to do the general animations next, but
I really have no current way to import multiple animations into Blender
yet, so the animation is kind of wonky.  I want to work on importing
multiple TimeSensors/Blender actions, but I haven't gotten to it yet.  I
suggest using the original texture instead of the Blender export to glTF,
if that is possible.
