<tt>glutTimerFunc</tt> registers the timer callback func to be triggered in at least msecs milliseconds.
The <i><tt>value</tt></i> parameter to the timer callback will be the value of the <i><tt>value</tt></i>
parameter to <tt>glutTimerFunc</tt>. Multiple timer callbacks at same or differing times may be registered
simultaneously.
</p><p>
The number of milliseconds is a lower bound on the time before the callback is generated. GLUT attempts to deliver the
timer callback as soon as possible after the expiration of the callback's time interval.
</p><p>
There is no support for canceling a registered callback. Instead, ignore a callback based on its value parameter when
it is triggered.
