The abstract base class for views.
A view is a rectangle on the graphic device into which drawing is done. Derived classes provide a concrete implementation based on some graphics toolkit. Examples are the QtView and EpsView classes.
A view is an Observer of a PlotterBase object, the base class of plotters. When it receives the Observer::update message, it initiates drawing by calling back the PlotterBase object with a pointer to itself. Drawing can also be initiated by an application by calling the PlotterBase object with view. For example, an EPSF file can be generated by a plotter by calling it with an EpsView.
Views are responsible for the translation from the data coordinate space used by the PlotterBase object to the graphics device coordinate space. They maintain their own coordinate system as float
objects to be compatible with scalable graphics tool kits such as Postscript.
