Timestamp:

Author:

Message:

Added --color r g b a, --wall-color r g b a, --back-color r g b a options for setting the colours of faces via materials.
and --image filename, --wall-image filename, --back-image filename options to set the textures used, note, texcoords are not currently set up so texels used will be 0,0.
