    	Added thumbnail image preview functions.
    	Previews are visible on the L&C&P dialogs as well as in the
    	drawables/channels/ menus generated for plugins
    	(see the bumpmap & Mapobject plugins).
    
    	PDB interface exists to simply extract a thumbnail preview
    	of a given size. This is much quicker & more efficient
    	than getting the image data tile-by-tile if you only need a small
    	image since a "preview cache" has been implemented. This cache also
    	reduces the number of times the tiles cached is scanned since smaller
    	previews are always generated from large ones if they exists and
    	are valid.
    
    	Some possible usages (I don't intend to implement these ideas. Just
    	suggestions). More plugins using the thumbnail preview (ie any that
    	use multiple images). Indication of "active image" somewhere.....
    	Actually almost anywhere a drawable/image name appears.
