	* app/commands.[ch]
	* app/edit_selection.c
	* app/gdisplay.[ch]
	* app/gdisplay_ops.[ch]
	* app/image_render.c
	* app/info_window.c
	* app/magnify.c
	* app/menus.c
	* app/scale.c: image rendering now happens with float scale
	factors, independent in X and Y axes.  Turning on dot-for-dot in view
	menu does what gimp always used to do (ie one image pixel becomes
	one monitor pixel).  Dot-for-dot is on by default so people
	shouldn't notice any difference unless they load an image that's
	not at 72 dpi and also turn off dot-for-dot.

	* app/app_procs.c
	* app/gimprc.[ch]
	* app/preferences_dialog.c: new gimprc options
	(monitor-xresolution <float>) and corresponding
 	(monitor-yresolution <float>).  Uglyness in preferences dialog to
	add a "Monitor" page to the notebook, allowing user to set their
	monitor's resolution or take it from the X server instead.  This
	badly needs cleaned up :(

	* plug-ins/newsprint/newsprint.c: oops - this hasn't been working
	for grayscale images since my last checkin.  Now fixed.
