Textured Cube

# A textured cube: a picture from a file, wrapped round a turning crate.
# Shows: THREE.TextureLoader().load() with a path beside the scene, and map= on a material.
# Drag to turn it.
#
# Run it:   pyctures run textured_cube.py
# Share it: pyctures build textured_cube.py -o site/   (textures/crate.png goes with it)
