	New "navigator" image (accessed via <Image>/Window Nav..). This gives
	an outline of the location of the current view on an image. Eg if your
	image window is only showing part of an image then the Window Navigation	window will outline the area viewed. You can "drag" the outlined
	square around the viewport and the main image will scroll. Additional
	a single click outside the square will center the image at that
	location.

	Also started to add additional information to a new page inside the
	Window information dialog (currently only pixel value is shown).

	Both these features are currently work in progress and unfinished.
	In particular the Navigator does not keep in step with changes
	to the basic image (however it does keep in step with image size changes	and if you modify the size of the image viewing window). It also
	does not display the transparent areas of images very nicely.
