COMMAND NAME:

        VPTOP

USAGE:

        VPTOP <pt>

        This command is used to expose a viewport in the graphics area.
The point selects the closest corner of
the closest viewport to bring to the top of the viewport hierarchy
(if covered by another viewport).

        You cannot expose the the main graphics window with VPTOP -
you can only use VPTOP on a viewport which was
created by the VPADD or VPCOPY commands.

        The effect of this command can also be achieved
by pressing a mouse button on a viewport's border.
