[x3d-public] Request for RenderedTexture

[John Carlson]

Perhaps Viewpoint should have the trigger and url, to download (filename)
or uploading the X3D scene or Texture of the Viewpoint?   Watch recursion
though.

See my softbody2 demo for downloading a .glb.  Why not X3D as well?

Thanks all for revealing this node!

One could specify whether one wanted a Texture, GlTF or X3D scene to be
captured.
