/**
* @class vtkInteractorStyleFlight
* @brief provides flight motion routines
*
*
* Left mouse button press produces forward motion.
* Right mouse button press produces reverse motion.
* Moving mouse during motion steers user in desired direction.
* Keyboard controls are:
* Left/Right/Up/Down Arrows for steering direction
* 'A' forward, 'Z' reverse motion
* Ctrl Key causes sidestep instead of steering in mouse and key modes
* Shift key is accelerator in mouse and key modes
* Ctrl and Shift together causes Roll in mouse and key modes
*
* By default, one "step" of motion corresponds to 1/250th of the diagonal
* of bounding box of visible actors, '+' and '-' keys allow user to
* increase or decrease step size.
