[x3d-public] gltf and x3d

[John Carlson]

Here is a first cut at converting GLTF to XML & DOM in node.js:

No guarantees, and very little testing.

I probably would target as a first step ExternalGeometry or
equivalent. Although glTF geometries could be represented as one of
X3D Geometry nodes, it would seem to make sense to avoid translation
to x3d fields and then back to GL data types ?

I could get ExternalGeometry for glTF 2.0 working in x3dom:

https://x3dom-gltf2-scratch.glitch.me/

has both, a glTF 1.0 ExternalShape and a glTF 2.0 ExternalGeometry (the duck).

It is still a bit hacky, mostly because it is tacked on to the
existing glTF 1.0 code. But it works and I learned the basics.

I will see if I can make some progress on PBR material support for
ExternalShape but if I cannot I will clean this up and PR it for x3dom
dev availability.
