From JavaScript: 3D

# Brought across from JavaScript: the classic spinning cube from a three.js
# example, line for line in Python.
# Shows: new X() becomes X(), {color: ...} becomes color=..., and the
# animation loop becomes draw().
# See docs/from-javascript.md for the JavaScript it came from.
#
# Run it:   pyctures run from_javascript_3d.py
# Share it: pyctures build from_javascript_3d.py -o site/
