define API for picking subclasses
vtkAbstractPicker is an abstract superclass that defines a minimal API for its concrete subclasses. The minimum functionality of a picker is to return the x-y-z global coordinate position of a pick (the pick itself is defined in display coordinates).
The API to this class is to invoke the Pick() method with a selection point (in display coordinates - pixels) and a renderer. Then get the resulting pick position in global coordinates with the GetPickPosition() method.
vtkPicker fires events during the picking process. These events are StartPickEvent, PickEvent, and EndPickEvent which are invoked prior to picking, when something is picked, and after all picking candidates have been tested. Note that during the pick process the PickEvent of vtkProp (and its subclasses such as vtkActor) is fired prior to the PickEvent of vtkPicker.
