[x3d-public] Normal vectors for points and lines?

[Don Brutzman]

It would seem that we are going to allow Normal nodes in PointSet nodes - not sure if consensus was declared on that yet.  Any contrary issues will be good to know.

For example: X3dMeshDesignPattern.x3d
https://x3dgraphics.com/examples/X3dForAdvancedModeling/Scanning/X3dMeshDesignPatternIndex.html

Wondering, will we allow Normal nodes within LineSet and IndexedLineSet also?  (They are defined in the example also.)

Of note is that X_ITE renders scene in the preceding page correctly, no complaints about Normal nodes.

Seems logical to consistently allow Normal with all such geometry nodes, preserving data-structure patterns also helps preserve data.

IF that is agreeable then I will update DOCTYPE x3d-4.0.dtd and schema x3d-4.0.xsd and X3DUOM accordingly.
  
How to render lines with normals would then seem to be another capability to integrate in revised rendering definitions of the X3Dv4 specification.

all the best, Don
