211HoverManipulator is a MatrixManipulator which provides a camera motion model using mouse and keyboard,
212designed for flythrough applications (eg. architectural visualisation).
213This class was based on FlightManipulator and inspired by the OpenGL Performer (TM) 'fly' navigation mode.
214
215<P>Mouse input:
216Dragging the middle mouse button changes the orientation of the camera.
217While holding down the middle mouse button, you increase/decrease flying speed using the left and
218right mouse buttons. Pressing the left and right buttons simultaneously works as a brake.
219
220<P>Keyboard input:
221Space - stops all motion immediately
222Arrow keys - move the camera parallel to the ground plane. Holding two 'opposing' arrow keys works as a
223brake.
224'r' or 'R' - return the camera to the 'home' position
