SYNOPSIS:
    VOL_CUT x y z wx wy wz|'cube'

DESCRIPTION:
    Cuts down a volume to the rectangular bounding box that starts
    at x/y/z and is sized wx,wy,wz.
    If you give "cube" (c will suffice) as the first parameter,
    it will try to infer the smallest possible volume containing
    all solid (depth=0) voxels.
    This is useful for reducing size of the volume and thus also
    speeding up rendering.

    VOL_SCALE, VOL_INFLATE
