// .NAME vtkXYPlotWidget - 2D widget for manipulating a XY plot
// .SECTION Description
// This class provides support for interactively manipulating the position,
// size, and orientation of a XY Plot. It listens to Left mouse events and
// mouse movement. It will change the cursor shape based on its location. If
// the cursor is over an edge of thea XY plot it will change the cursor shape
// to a resize edge shape. If the position of a XY plot is moved to be close to
// the center of one of the four edges of the viewport, then the XY plot will
// change its orientation to align with that edge. This orientation is sticky
// in that it will stay that orientation until the position is moved close to
// another edge.
