[x3d-public] Blender 4.0 io_scene_x3dv exporter patch

[John Carlson]

I made a change to the io_scene_x3dv exporter for Blender 4.0, and things
seem to be working.  I would like human confirmation that this is the right
thing to do.   There are 4 mentions of distance in the Blender PointLight
API documentation.

I don't know enough about PointLight.radius in X3D to know if it's the same
as PointLight.cutoff_distance in Blender.

If no one else volunteers, I can make a similar change to io_scene_x3d, I
just need confirmation that I'm choosing the right thing to do, below.

This has been updated for Blender 4.0, but I haven't tested much of the GUI:

https://github.com/coderextreme/BlenderX3DSupport/tree/main/io_scene_x3dv

You'll have to make a zip of the folder, then install in Blender GUI.

The focus of the io_scene_x3dv plugin has been 1) porting to x3d.py 2)
incorporating glTF-like file structure 3) HAnim+animation

Bug reports welcome

Thanks!

John
