/**
* Moves the View around a point of interest when the mouse is dragged with
* a mouse button pressed. Includes rotation, zoom, and translation
* actions. Zooming can also be obtained by using mouse wheel.
*
* This behavior must be added to the ViewingPlatform
* using the ViewingPlatform.setViewPlatformBehavior method.
*
* The rotate action rotates the ViewPlatform around the point of interest
* when the mouse is moved with the main mouse button pressed. The
* rotation is in the direction of the mouse movement, with a default
* rotation of 0.01 radians for each pixel of mouse movement.
*
* The zoom action moves the ViewPlatform closer to or further from the
* point of interest when the mouse is moved with the middle mouse button
* pressed (or Alt-main mouse button on systems without a middle mouse button).
* The default zoom action is to translate the ViewPlatform 0.01 units for each
* pixel of mouse movement. Moving the mouse up moves the ViewPlatform closer,
* moving the mouse down moves the ViewPlatform further away.
*
* By default, the zoom action allows the ViewPlatform to move through
* the center of rotation to orbit at a negative radius.
* The STOP_ZOOM constructor flag will stop the ViewPlatform at
* a minimum radius from the center. The default minimum radius is 0.0
* and can be set using the setMinRadius method.
*
* The PROPORTIONAL_ZOOM constructor flag changes the zoom action
* to move the ViewPlatform proportional to its distance from the center
* of rotation. For this mode, the default action is to move the ViewPlatform
* by 1% of its distance from the center of rotation for each pixel of
* mouse movement.
*
* The translate action translates the ViewPlatform when the mouse is moved
* with the right mouse button pressed (Shift-main mouse button on systems
* without a right mouse button). The translation is in the direction of the
* mouse movement, with a default translation of 0.01 units for each pixel
* of mouse movement.
*
* The sensitivity of the actions can be scaled using the
* setActionFactor() methods which scale
* the default movement by the factor. The rotate and translate actions
* have separate factors for x and y.
*
* The actions can be reversed using the REVERSE_ACTION
* constructor flags. The default action moves the ViewPlatform around the
* objects in the scene. The REVERSE_ACTION flags can
* make the objects in the scene appear to be moving in the direction
* of the mouse movement.
*
* The actions can be disabled by either using the
* DISABLE_ACTION constructor flags or the
* setActionEnable methods.
*
* The default center of rotation is (0, 0, 0) and can be set using the
* setRotationCenter() method.
*
* @since Java 3D 1.2.1
