I'm confused and dont understand what you mean.  Do you mean that the
trackball style itself is deprecated or will you rework the trackball
code so that it is written differently?  I'm opposed to removing the
trackball style.  Why should the trackball style be deprecated and not
the joystick? I.e. will the users be able to use
interactorStyleSwitch, hit the 't' key and see trackball interaction?

thanks,
