[x3d-public] An annotations example and project

[John Carlson]

MIchalis, this is NOT a bug report in view3dscene, rather it supports a
success!

Experiences with latest download of Castle Game engine:

$ Downloads/view3dscene-4.2.0-win64-x86_64/view3dscene/view3dscene.exe
X3DJSONLD/src/main/glTF/Astronaut.glb

Works great, and in color!

Convert to X3D XML from view3dscene, there's no color/texture in X3DOM, but
shape looks good loading into X3DOM!

Can someone do annotations in CGE/view3dscene? Can someone make sure that
color (PBR, Textures from view3dscene is loaded into X3DOM?

Loaded Astronaut.x3d into view3dscene, looks great, with color.

Will try loading VRML into X_ITE next
