image <-scale: size -> image

New image scaled to the given dimensions. Scaling is done once at copy time, so passing a target size avoids the rounding problems of a multiplicative factor. To magnify by a factor:

magnify(Im, Factor, Magnified) :-
        get(Im, size, size(W, H)),
        NW is round(W * Factor),
        NH is round(H * Factor),
        get(Im, scale, size(NW, NH), Magnified).
