	Fixed bug 2194, no scrollbars in image view
	Fixed bug 2215, image viewer needs to erase background
	when loading image.

	I fixed these bugs by writing a new image component.  Is this bad?
	I don't know.  What is bad is the current state of the EOG bonobo
	component.  I don't think it is worth our time to fix it right now.
	This component will also support the zoomable interface when
	Maciej finishes the work there. It is doubtful the EOG bonobo
	component would have a Nautilus specific dependency.
