{ GEO X3D component.

  Note that this is slightly incompatible with the VRML 97 definition of
  the same nodes. And this incompatibility is not fixed here.
  When (if ever) I decide to implement Geo, it will be X3D-compatible only.
  Since I didn't ever implement VRML 97 GEO component, and I do not have current
  plans to implement X3D GEO component, and GEO is optional anyway in VRML 97,
  I decided GEO is just not important enough for me to try to
  parse VRML 97 GEO nodes.

  Incompatible differences in VRML 97 are mainly caused by the fact
  that double-precision field types were not available in VRML 97.
  And GEO really needed them. So many fields had to be defined as SFString
  type, while in X3D that are SFDouble, SFVec2d, SFVec3d etc.
  Examples:
  - GeoElevationGrid: xSpacing, zSpacing, geoGridOrigin
  - GeoOrigin: geoCoords
