getPickedPoints : $ -> L POINT
++ getPickedPoints(x)
++ returns a list of small floats for the points the
++ user interactively picked on the viewport
++ for full integration into the system, some design
++ issues need to be addressed: for example, how to go through
++ the GraphImage interface, how to default to graphs, etc.

++ of the domain \spadtype{TwoDimensionalViewport} whose
++ contents are empty.

++ sets the state of the characteristics for the graph indicated
++ by \spad{num} in the given two-dimensional viewport v, of domain
++ \spadtype{TwoDimensionalViewport}, to the values given as
++ parameters. The scaling of the graph in the x and y component
++ directions is set to be \spad{sX} and \spad{sY}; the window
++ translation in the x and y component directions is set to be
++ \spad{dX} and \spad{dY}; The graph points, lines, bounding box,
++ axes, or units will be shown in the viewport if their given
++ parameters \spad{pts}, \spad{lns}, \spad{box}, \spad{axes} or
++ \spad{un} are set to be \spad{1}, but will not be shown if they
++ are set to \spad{0}. The color of the axes and the color of the
++ units are indicated by the palette colors \spad{axesC} and

++ the graphs, of the domain \spadtype{GraphImage}, which are

++ are shown.

++ viewport window, v of domain \spadtype{TwoDimensionalViewport}.

++ indicated two-dimensional viewport, v, which is of domain
++ \spadtype{TwoDimensionalViewport}, to be the graph, \spad{gi}

++ is called to create the an updated viewport v.
getGraph : ($,PI) -> G
++ getGraph(v,n) returns the graph which is of the domain
++ \spadtype{GraphImage} which is located in graph field n

++ domain \spadtype{TwoDimensionalViewport}.
axes : ($,PI,STR) -> Void
++ axes(v,n,s) displays the axes of the graph in field n of
++ the given two-dimensional viewport, v, which is of domain
++ \spadtype{TwoDimensionalViewport}, if s is "on", or does
++ not display the axes if s is "off".
axes : ($,PI,PAL) -> Void

++ units(v,n,s) displays the units of the graph in field n of
++ the given two-dimensional viewport, v, which is of domain
++ \spadtype{TwoDimensionalViewport}, if s is "on", or does
++ not display the units if s is "off".
units : ($,PI,PAL) -> Void
++ units(v,n,c) displays the units of the graph in field n of
++ the given two-dimensional viewport, v, which is of domain
++ \spadtype{TwoDimensionalViewport}, with the units color set to
++ the given palette color c.

region : ($,PI,STR) -> Void
++ region(v,n,s) displays the bounding box of the graph in
++ field n of the given two-dimensional viewport, v, which is
++ of domain \spadtype{TwoDimensionalViewport}, if s is "on",
++ or does not display the bounding box if s is "off".

++ connect(v,n,s) displays the lines connecting the graph
++ points in field n of the given two-dimensional viewport, v,
++ which is of domain \spadtype{TwoDimensionalViewport}, if s

controlPanel : ($,STR) -> Void
++ controlPanel(v,s) displays the control panel of the given
++ two-dimensional viewport, v, which is of domain
++ \spadtype{TwoDimensionalViewport}, if s is "on", or hides
++ the control panel if s is "off".
close : $ -> Void
++ close(v) closes the viewport window of the given

++ dimensions(v,x,y,width,height) sets the position of the
++ upper left-hand corner of the two-dimensional viewport, v,
++ which is of domain \spadtype{TwoDimensionalViewport}, to
++ the window coordinate x, y, and sets the dimensions of the
++ window to that of \spad{width}, \spad{height}. The new
++ dimensions are not displayed until the function
++ \spadfun{makeViewport2D} is executed again for v.
scale : ($,PI,F,F) -> Void
++ scale(v,n,sx,sy) displays the graph in field n of the given
++ two-dimensional viewport, v, which is of domain
++ \spadtype{TwoDimensionalViewport}, scaled by the factor \spad{sx}
++ in the x-coordinate direction and by the factor \spad{sy} in
++ the y-coordinate direction.

++ two-dimensional viewport, v, which is of domain
++ \spadtype{TwoDimensionalViewport}, translated by \spad{dx} in
++ the x-coordinate direction from the center of the viewport, and
++ by \spad{dy} in the y-coordinate direction from the center.
++ Setting \spad{dx} and \spad{dy} to \spad{0} places the center
++ of the graph at the center of the viewport.

++ show(v,n,s) displays the graph in field n of the given
++ two-dimensional viewport, v, which is of domain
++ \spadtype{TwoDimensionalViewport}, if s is "on", or does not

++ is of domain \spadtype{TwoDimensionalViewport}, with the upper
++ left-hand corner of the viewport window at the screen
++ coordinate position x, y.
update :($,G,PI) -> Void
++ update(v,gr,n) drops the graph \spad{gr} in slot \spad{n}
++ of viewport \spad{v}. The graph gr must have been
++ transmitted already and acquired an integer key.
resize : ($,PI,PI) -> Void
++ resize(v,w,h) displays the two-dimensional viewport, v, which
++ is of domain \spadtype{TwoDimensionalViewport}, with a width
++ of w and a height of h, keeping the upper left-hand corner
++ position unchanged.
write : ($,STR) -> STR
++ write(v,s) takes the given two-dimensional viewport, v, which
++ is of domain \spadtype{TwoDimensionalViewport}, and creates
++ a directory indicated by s, which contains the graph data
++ files for v.
write : ($,STR,STR) -> STR
++ write(v,s,f) takes the given two-dimensional viewport, v, which
++ is of domain \spadtype{TwoDimensionalViewport}, and creates

++ files for v and an optional file type f.
write : ($,STR,L STR) -> STR
++ write(v,s,lf) takes the given two-dimensional viewport, v, which
++ is of domain \spadtype{TwoDimensionalViewport}, and creates
++ a directory indicated by s, which contains the graph data
++ files for v and the optional file types indicated by the list lf.
reset : $ -> Void
++ reset(v) sets the current state of the graph characteristics
++ of the given two-dimensional viewport, v, which is of domain
++ \spadtype{TwoDimensionalViewport}, back to their initial settings.
key : $ -> I
++ key(v) returns the process ID number of the given two-dimensional
++ viewport, v, which is of domain \spadtype{TwoDimensionalViewport}.
