	// Whenever Maya loads a new icon, it caches the image and never looks
	// at the file again.  This can be annoying when you are using icons as
	// swatches which can be updated during the course of a session.
	//
	// Maya does provide a 'reloadImage' MEL command to reload an icon from
	// its file, into a specific UI control.  However, there is no way to
	// determine whether the icon *needs* to be reloaded.  So you're stuck
	// with always doing the reload, which results in doubled load time the
	// first time the icon is used, and an extra load even when it hasn't
	// changed.
	//
	// This method gets around that by allowing you to register an icon
	// whenever you use it.  It compares timestamps and returns true if the
	// icon needs to be reloaded.
	//
