- * 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.
