 *    possible to minimize CPU usage for the current application. The
 *    event loop is run implicitly thru APIs like ReceiveNextEvent,
 *    RunApplicationEventLoop, or even WaitNextEvent. It can also be
 *    run explicitly thru a call to RunCurrentEventLoop. Each
 *    preemptive thread can have an event loop. Cooperative threads

 *  
 *  Discussion:

{
 *  GetCFRunLoopFromEventLoop()
 *  
 *  Discussion:
 *    Returns the corresponding CFRunLoopRef for the given EventLoop.
 *    This is not necessarily a one-to-one mapping, hence the need for
 *    this function. In Carbon, all cooperative threads use the same
 *    run loop under the covers, so using CFRunLoopGetCurrent might
 *    yield the wrong result. In general, you would only need to use
 *    this function if you wished to add your own sources to the run
 *    loop. If you don't know what I'm talking about, then you probably
 *    don't need to use this.

 *  
 *  Summary:

 *  
 *  Discussion:
 *    At any point in the handling of user input, there are two
 *    different mouse button states: the queue-synchronized state and
 *    the hardware state. The hardware state reflects the actual
 *    current state of the mouse attached to the user's machine. The
 *    queue-synchronized state reflects the state according to the
 *    events that have been processed at that point by the application.
 *    These two states may be different if there are unprocessed events
 *    in the event queue, or if events are being artificially
 *    introduced into the event queue from an outside source.
 *    GetCurrentEventButtonState returns the queue-synchronized button
 *    state. This state is determined by user input events that are
 *    sent through the event dispatcher target; whenever a user input
 *    event (mouse or keyboard) is handled by the Carbon event
 *    dispatcher, its button state is recorded, and that button state
 *    will be returned by GetCurrentEventButtonState. 
 *    
 *    The "current event" referenced in the API name is the event most
 *    recently dispatched through the event dispatcher target, which is
 *    not necessarily the event that your event handler is handling.
 *    For example, if a mouse-down event occurs, and you have a handler
 *    for the kEventWindowHandleContentClick event that is generated
 *    from the mouse-down, then the button state will be that which was
 *    attached to the mouse-down. The ContentClick event itself does
 *    also have MouseButton and MouseChord parameters, which are copied
 *    from the the mouse-down event, but GetCurrentEventButtonState
 *    returns the button state from the mouse-down, not from the
 *    ContentClick event, since it was the mouse-down that was most
 *    recently dispatched through the event dispatcher. Usually, this
 *    is the behavior that you want anyways. 
 *    
 *    Note that events that are not sent through the event dispatcher
 *    target will not update the current event button state. Also, note
 *    that events arriving from outside the application, such as an
 *    AppleEvent or an Accessibility event, also will not update the
 *    modifiers. If your application modifies its behavior based on
 *    button state, we recommend that you parameterize your core code
 *    with the event buttons, and determine the button state based on
 *    the origin of the behavior request. For a request that originates
 *    directly from user input, you can use GetCurrentEventButtonState,
 *    but for a request that originates from an AppleEvent or
 *    Accessibility event, you would probably use no button state, or
 *    perhaps just left-button-pressed. 
 *    
 *    It is generally better to use this API than to use the Button
 *    function or the GetCurrentButtonState function (which return the
 *    hardware state). This gives a more consistent user experience
 *    when the user input queue is being remoted controlled or
 *    manipulated via non-hardware event sources such as speech or
 *    AppleEvents; using GetCurrentEventButtonState is also much faster
 *    than using Button or GetCurrentButtonState.
 *    
 *    Note that GetCurrentEventButtonState only returns a valid button

 *  EventLoopTimerRef
 *  
 *  Discussion:
 *    An EventLoopTimerRef represents what we term a 'timer'. A timer
 *    is a function that is called either once or at regular intervals.
 *    It executes at task level and should not be confused with Time
 *    Manager Tasks or any other interrupt-level callback. This means
 *    you can call Toolbox routines, allocate memory and draw. When a
 *    timer 'fires', it calls a callback that you specify when the
 *    timer is installed. Timers in general have two uses - as a
 *    timeout mechanism and as a periodic task. An everyday example of
 *    using a timer for a timeout might be a light that goes out if no
 *    motion is detected in a room for 5 minutes. For this, you might
 *    install a timer which will fire in 5 minutes. If motion is
 *    detected, you would reset the timer fire time and let the clock
 *    start over. If no motion is detected for the full 5 minutes, the
 *    timer will fire and you could power off the light. A periodic
 *    timer is one that fires at regular intervals (say every second or
 *    so). You might use such a timer to blink the insertion point in
 *    your editor, etc. One advantage of timers is that you can install
 *    the timer right from the code that wants the time. For example,
 *    the standard Toolbox Edit Text control can install a timer to

{
 *  InstallEventLoopIdleTimer()
 *  
 *  Discussion:
 *    Installs a timer onto the event loop specified. Idle timers are
 *    only called when there is no user activity occuring in the
 *    application. This means that the user is not actively
 *    clicking/typing, and is also not in the middle of tracking a
 *    control, menu, or window. TrackMouseLocation actually disables
 *    all idle timers automatically for you.
 *  
 *  Mac OS X threading:
 *    Thread safe
 *  
 *  Parameters:
 *    
 *    inEventLoop:
 *      The event loop to add the timer.
 *    
 *    inDelay:
 *      The delay before firing this timer after a user input event has
 *      come in. For example, if you want to start your timer 2 seconds
 *      after the user stops typing, etc. you would pass 2.0 into this
 *      parameter. Each time the user types a key (or whatever), this
 *      timer is reset. If we are considered to be idle when an idle
 *      timer is installed, the first time it fires will be inDelay
 *      seconds from the time it is installed. So if you installed it
 *      in the middle of control tracking, say, it wouldn't fire until
 *      the user stopped tracking. But if you installed it at app
 *      startup and the user hasn't typed/clicked, it would fire in
 *      inDelay seconds. On Mac OS X 10.3 and earlier, the delay must
 *      be greater than zero. On Mac OS X 10.4 and later, the delay
 *      must be greather than or equal to zero. You cannot use
 *      kEventDurationForever for the delay.

 *    inInterval:
