[X3D-Ecosystem] Layout and Layering component loading in X3DJSAIL.

[John Carlson]

I do not have small examples of Layout, and my examples mainly inherit from
Christoph Valentin, so perhaps he could volunteer a small example?

I am attaching the least problematic ones that display in sunrize (x_ite)
and freewrl respectively with errors, which someone could pare down.  The
white letters and "=" should be draggable with a mouse in the product, and
those parameters should affect the central shape.  When you drag the
letters, a parameter value appears to the right of the "=".  At least the
dragging (sliders) works in both examples.

But really, Christoph has done some marvels.  Perhaps he's more ready to
contribute than I am.

I have two examples of Layering, mostly the work with the 2 Menus when we
were converting FACS to HAnimDisplacer.

So, my examples may need more crafting with X3D-Edit.  Plus, they have
licensed resources, like shaders and images.  I believe that shaders and
images can be removed or replaced with little effect on the Layout stuff.

Once we have a baseline for a "slider" from Christoph, I can add the Proto
work I did with sliders, which is more advanced.

Thanks, Christoph,

John
