[X3D-Ecosystem] PREF_FLAT True or False?

[John Carlson]

I am primarily interested in using Blender to convert HAnim X3D to gltf and
glb, and have animations work.

We have an io_scene_x3d exporter and an io_scene_x3dv exporter.  The latter
is valuable as it generates both XML and VRML through the use of
x3d(v).py.  I am working towards dual use of the exporter with both my X3D
loader and other blender files.  The intent of the loader is to pass X3D
scenegraph through blender, so we can have stuff like billboards, touch
sensors, etc. on output.

It seems that HAnim import into blender might or might not work depending
on whether normal objects can have vertex groups.

Sounds like we should get both import and export working
with TextureTransform.
