// .NAME vtkImageActorPointPlacer - Converts 2D display positions to world positions such that they lie on an ImageActor
// .SECTION Description
// This PointPlacer is used to constrain the placement of points on the
// supplied image actor. Additionally, you may set bounds to restrict the
// placement of the points. The placement of points will then be constrained
// to lie not only on the ImageActor but also within the bounds specified.
// If no bounds are specified, they may lie anywhere on the supplied ImageActor.

// Description:
// Given and renderer and a display position in pixels,
// find a world position and orientation. In this class
// an internal vtkBoundedPlanePointPlacer is used to compute
// the world position and orientation. The internal placer
// is set to use the plane of the image actor and the bounds
// of the image actor as the constraints for placing points.

// Update the world position and orientation according the

// Description:
// A method for configuring the internal placer according
// to the constraints of the image actor.
// Called by the representation to give the placer a chance
// to update itself, which may cause the MTime to change,
// which would then cause the representation to update
// all of its points
