	//		onload = function() { onload2(); cutomFunction1(); cutomFunction2(); }			//

	// Note: Any function with a for loop will keep the remaining calls in its on*_list		//
	// array from executing IF a globally-scoped i variable is used, as is the norm. In		//
	// such a case use: on*_list.unshift('func'); to add functions to the end of the list.	//
