webview python program version 3.1

[Roger Kaufman]

Hi All,

I have migrated my site to Wagyx's multi-off-view. Thanks to Wagyx for
the new viewer!

In kind, I have now updated webview to 3.1 so the offview.py python can
take advantage of the new features.

Version 3.1
06-18-24 Roger Kaufman <polyhed...@gmail.com>
         Changes
            offview.py
               Check color input strings for 6 to 8 hex digits or
'invisible'
               Allow invisible backgrounds

Transparencies of individual faces, edges and vertices are now possible.
The effect makes the models look the same as they do with the X_ite vrml
browser.

conway etI -m map_0:0:0:red:darkorange1:yellow:xffffffcc | offview.py

the same command could be directed to the X_ite browser with

conway etI -m map_0:0:0:red:darkorange1:yellow:xffffffcc | off2vrml |
x3dview.py

The python scripts have been tested under Windows WSL2 running Ubuntu
and native Ubuntu. Does anyone have any experience in running python in
native Windows?

The help is below.
