* Sets the startup notification ID for a display.
*
* This is usually taken from the value of the DESKTOP_STARTUP_ID
* environment variable, but in some cases (such as the application not
* being launched using exec()) it can come from other sources.
*
* If the ID contains the string "_TIME" then the portion following that
* string is taken to be the X11 timestamp of the event that triggered
* the application to be launched and the GDK current event time is set
* accordingly.
*
* The startup ID is also what is used to signal that the startup is
* complete (for example, when opening a window or when calling
* gdk_notify_startup_complete()).
*
* Since: 3.0
