x3d v.4 should support a new, web Mercator geoSystem.

https://en.wikipedia.org/wiki/Web_Mercator

is the projection used for all web mapping (slippy maps). Having it
available will make it possible to use such maps in a precise manner within
the geospatial component.

Section 25.2.3

http://www.web3d.org/documents/specifications/19775-1/V3.3/Part01/components/geodata.html#Specifyingaspatialreference

will need to be amended by

"*WM*" - Web Mercator. No additional arguments are supported. An example
spatial reference frame definition of this format is [ "WM" ].

I can come up with an entry for section 25.2.4. as well.
