[x3d-public] Proposed new Profile

[Andreas Plesch]

I also think such a profile could be very useful and successful.

Collada is another commonly used format which may be worth mentioning.

view3dscene can import collada and, I believe .obj format, and export
static, conforming, x3d pretty well. I just converted some of the source
models used for glTF testing to x3d this way:

Cheers, Andreas
