[x3d-public] Blender 4.0 io_scene_x3dv exporter patch

[John Carlson]

Some notes on current Blender 4.0 BVH imports and io_scene_x3dv exports.
This has nothing to do with x3d-edit.

If you load Pirouette.bvh from the archives, prepare to zoom in a long
distance if you don’t have model centering, both in Blender and view3scene
on exported files.  I didn’t see any keyframing in Blender, and I didn’t
check for orientation interpolators on export.

The skeleton may not show up in an x3d viewer if your joints don’t match
HAnim.  I believe Doug is thinking about, or has something for remapping
joint names to HAnim.

It would be good to have some BVH examples with HAnim joints.  I’ll try
exporting Gramps as BVH from blender.
