SYNOPSIS:
    VOL_SCALE vector

DESCRIPTION:
    Set the scaling of the current volume to the three given values
    for the three axis of the volume. This is required for volumes
    with nonisotrop voxels. It is not possible to scale the volume
    along axis other than its principal axis. Resample the volume,
    if you really really want this.
