snap correctly to the bottom and right sides of the rectangle. Also snap

2003-05-18  Michael Natterer  <mitch@gimp.org>

	* app/core/gimpimage-guides.c (gimp_image_snap_rectangle): snap
	correctly to the bottom and right sides of the rectangle. Also
	snap to the closer guide if we snap twice on one axis.
	Fixes bug #113233.

	All snapping functions: use ROUND() instead of truncating the
	double coords.
