[X3D-Ecosystem] Layout and Layering component loading in X3DJSAIL.

[Don Brutzman]

Focusing on Layout component nodes themselves:

We do not have any example scenes  in the archives showing each of the 5
Layout component nodes: Layout, LayoutGroup, LayoutLayer, ScreenFontStyle,
and ScreenGroup.

It would be good to have some simple examples showing these nodes in use,
so that we might test tools equivalently.

   - X3D Architecture, v4.1 draft, clause 36 Layout component
   -
   https://www.web3d.org/specifications/X3Dv4Draft/ISO-IEC19775-1v4.1-CD/Part01/components/layout.html

To be understandable, useful and repeatable, such examples should be pretty
terse (maybe a few dozen lines long).

Slogan that still holds true, even at our pretty-high level of
reliable maturity: "you get what you inspect, not what you expect."

Thanks in advance for all offers and efforts to establish a shared
baseline.  This will help X3D authors too.

all the best, Don
