[x3d-public] CoordinateInterpolator2D

[Andreas Plesch]

Just a note that x3dom does not currently implement
CoordinateInterpolator2D but as a non-standard/incompaible workaround
it is possible to CoordinateInterpolator instead. See example.

x3dom will just ignore the third/z  component of the coordinate when
routed to a Vec2f field.

Hopefully the base64 dataurl below survives the email transport given
the original intention of uuencoding.
