* Indicates whether Joystick events are being used by ANY window.
*
* The current mechanism is to walk all of the windows and ask if
* there is a joystick callback. Certainly in some cases, maybe
* in all cases, the joystick is attached to the system and accessed
* from ONE point by GLUT/freeglut, so this is not the right way,
* in general, to do this. However, the Joystick code is segregated
* in its own little world, so we can't access the information that
* we need in order to do that nicely.
* there is a joystick callback. We have a short-circuit early
* return if we find any joystick handler registered.
*
* Some alternatives:
* * Store Joystick data into freeglut global state.
* * Provide NON-static functions or data from Joystick *.c file.
*
* Basically, the RIGHT way to do this requires knowing something
* about the Joystick. Right now, the Joystick code is behind
* an opaque wall.
* The real way to do this is to make use of the glutTimer() API
* to more cleanly re-implement the joystick API. Then, this code
* and all other "joystick timer" code can be yanked.
