SYNOPSIS:
    cutplane: a plane that can be used to cut away parts of the volume.

DESCRIPTION:
    Eccet can cut away parts of the volume to allow for looking
    at interesing areas without being obscured by other objects
    in the foreground.

    Cutplanes live in the global coordinate system and can be moved,
    and redefined as the user wishes. They can be mapped to renderers
    as the user wishes (only mapped cutplanes take effect) and most
    renderers support restricting the use of specific cutplanes to
    specific classes.
