* were last called and a time since the last loop, as well as a loop counter.
* The 'phase' parameter is deprecated and should be ignored.
*
* Your return value controls when you will next be called. Return 0 to stop
* receiving callbacks. Pass a positive number to specify how many seconds
* until the next callback. (You will be called at or after this time, not
* before.) Pass a negative number to specify how many loops must go by until
* you are called. For example, -1.0 means call me the very next loop. Try
* to run your flight loop as infrequently as is practical, and suspend it
* (using return value 0) when you do not need it; lots of flight loop
* callbacks that do nothing lowers x-plane's frame rate.
*
* Your callback will NOT be unregistered if you return 0; it will merely be
* inactive.
*
* The reference constant you passed to your loop is passed back to you.

* THREAD SAFETY: it is legal to call this routine from any thread under the
* following conditions:
*
* 1. The call must be between the beginning of an XPLMEnable and the end of
* an XPLMDisable sequence. (That is, you must not call this routine from
* thread activity when your plugin was supposed to be disabled. Since
* plugins are only enabled while loaded, this also implies you cannot run
* this routine outside an XPLMStart/XPLMStop sequence.)
*
* 2. You may not call this routine re-entrantly for a single flight loop ID.
* (That is, you can't enable from multiple threads at the same time.)
*
* 3. You must call this routine between the time after XPLMCreateFlightLoop
* returns a value and the time you call XPLMDestroyFlightLoop. (That is, you
* must ensure that your threaded activity is within the life of the object.
* The SDK does not check this for you, nor does it synchronize destruction of
* the object.)
*
* 4. The object must be unscheduled if this routine is to be called from a
* thread other than the main thread.
