[x3d-public] Support for specular maps (and more) in view3dscene, and Blender exporter to CommonSurfaceShader

[Andreas Plesch]

This is giving me a chance to try out SplineInterpolators, and it is fun. I
updated the moving light to smoothly turn around, and added a second
circling light. Both was possible with only a few lines using spline
interpolation, and no scripts.

Here is a question for spline experts. I could produce a path resembling a
circle with only three key values (start,middle, start) and key velocities,
using SplinePositionInterpolator. The velocities are tangential to the
path. It turns out that a velocity magnitude of about 4 times the intended
radius produces a good approximation of a circle. How would one produce an
exact circle path with SplinePositionInterpolator ?

updated but a little busy now:
