    This is an abstract class for device handles which are responsible

    for finalization i.e. to destroy underlying system resources, when the GC

    frees an object which has created some system object.

    Currently, these are forms and views (streams, cursors, colors and

    fonts could also make use of this class - however, for historical reasons,

    they continue to use their own private finalization machanisms. This may

    change in future versions).
