[x3d-public] Blender 3.0 import/export of HelloWorld.x3d

[Andreas Plesch]

Thanks, Vince, for looking up the situation. It turned out there was a
simple fix for the global problem, and I have some understanding now of how
the exporter works.

Texture coordinate export works and it is straightforward to manually
augment the Appearance with an ImageTexture or TextureProperties.

It may be possible to add the ImageTexture line to the exporter  Exporting
the texture image seems more involved.

Happy New Year 🎈,

Andreas
