// wxJoystickThread::HIDCallback (static)
//
// Callback for the native HID device when it recieves input.
//
// This is where the REAL dirty work gets done.
//
// 1) Loops through each event the queue has recieved
// 2) First, checks if the thread that is running the loop for 
//    the polling has ended - if so it breaks out
// 3) Next, it checks if there was an error getting this event from
//    the HID queue, if there was, it logs an error and returns
// 4) Now it does the real dirty work by getting the button states
//    from cookies 0-40 and axes positions/states from cookies 40-50
//    in the native HID device by quering cookie values.
// 5) Sends the event to the polling window (if any)
// 6) Gets the next event and goes back to (1)
