2005-01-03 Michael Natterer <mitch@gimp.org> Implemented "Snap to Canvas Edges" (fixes bug #152971) and "Snap to Active Path" (half way done): * app/core/gimpimage-snap.[ch]: added boolean snap_to_canvas and snap_to_vectors parameters (snap_to_vectors works fine when snapping to a point, but is unimplemented for snapping to a rectangle). * app/display/gimpdisplayshell.[ch] (struct GimpDisplayShell): added snap_to_canvas and snap_to_vectors booleans. * app/display/gimpdisplayshell-appearance.[ch]: added API to get/set them. * app/actions/view-actions.c * app/actions/view-commands.[ch] * app/widgets/gimphelp-ids.h: added actions, callbacks and help IDs. * menus/image-menu.xml.in: added them to Image->View.
