Detailed Description

SDL_AddTimer() callback for the hover event.

When this callback is called it pushes a new hover event in the event queue.

Parameters:

	interval	The time parameter of SDL_AddTimer.
	param	Pointer to a widget that's able to show the tooltip (will be used as a dispatcher).

Returns:

The new timer interval, 0 to stop. Small helper to keep a resource (boolean) locked.

Some of the event handling routines can't be called recursively, this due to the fact that they are attached to the pre queue and when the forward an event the pre queue event gets triggered recursively causing infinite recursion.

To prevent that those functions check the lock and exit when the lock is held otherwise grab the lock here.
