oops - should use the image resolution, not the screen resolution. D'oh! 

Wed Jan 27 21:52:43 GMT 1999  Austin Donnelly  <austin@gimp.org>

	* app/scale.c: oops - should use the image resolution, not the
	    screen resolution.  D'oh!

	* app/gimpdrawable.c: only merge shadow image if there actually is
	    one.

	* plug-ins/emboss/emboss.c: small optimisation: use
 	    gimp_drawable_mask_bounds() to calculate only the pixels that
 	    are actually in the selection.
