This is definitely not core type material. Also it's much better in the proper
header gimpimage-snap.h and the type name should reflect the file namespace,
especially as we make it public.
This commit also makes snap to grid and snap to vectors work off-canvas.
Since we now have off-canvas viewing, it just makes sense that snapping
would work there too.
Note that I disable snap to grid when "Show All" is OFF. I am actually
unsure this is right (as "Show All" is a view action, and we usually
don't change behavior based on view actions; for instance snap to guides
are not disabled if guides are hidden). Yet I noticed we do this in
various other features when off-canvas. We kind of use this view flag as
a switch for features working off-canvas (for instance, color picking
works off-canvas only when "Show All" is ON). So let's keep the same
logics for now at least.
Snap to guide or snap to vectors will always work though, because guides
and vectors are always visible off-canvas (even when "Show All" is OFF).
They always have been (visible, not snappable off-canvas; now they are
both).

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.
2004-02-23 Michael Natterer <mitch@gimp.org>
* app/core/gimpimage-snap.[ch]: return the snapped coordinates as
gdouble, not gint because we must not round the unsnapped axis
if only one axis snapped.
* app/display/gimpdisplayshell.[ch] (gimp_display_shell_snap_coords):
changed accordingly. Added boolean return value indicating "snapped".
* app/display/gimpdisplayshell-cursor.[ch]
(gimp_display_shell_update_cursor): take both display_x and _x and
(possibly snapped) image_x and _y. Use the snapped values for the
statusbar and the unsnapped ones for updating the info_window.
* app/display/gimpdisplayshell-callbacks.c
(gimp_display_shell_canvas_tool_events): applied modified patch
from Simon Budig which moves guide/grid snapping out of the
button_press/motion/button_release handlers and *always* snaps
the image_coords if the active_tool wants them to be snapped.
Makes sure that e.g. the brush preview is drawn at the right
place and fixes bug #134284.
Also pass both display_coords and image_coords to
gimp_display_shell_update_cursor().
2004-02-13 Simon Budig <simon@gimp.org>
* app/core/gimpimage-snap.[ch]: make the snapping width a
parameter of the snapping functions.
* app/display/gimpdisplayshell.c: make sure that the snapping
width always is 5 pixels in the view coordinates.
Fixes bug #134285
This fixes bug #65198
* app/core/Makefile.am
* app/core/core-types.h:
* app/core/gimpgrid.[ch]: added new class GimpGrid.
* app/core/core-enums.[ch]: added new enum GimpGridType.
* app/core/gimpimage-guides.[ch]: removed the gimp_image_snap_*()
functions...
* app/core/gimpimage-snap.[ch]: ...and added them here since they
are no longer guide specific.
* app/core/gimpimage-undo-push.[ch]: added
gimp_image_undo_push_image_grid()
* app/display/gimpdisplayshell-handlers.c:
* app/core/gimpimage.[ch]: added grid member to _GimpImage. Added
new signal "grid_changed", added gimp_image_grid_changed(),
gimp_image_get_grid() and gimp_image_set_grid().
* app/display/gimpdisplayshell-appearance.[ch]: added
gimp_display_shell_set_show_grid(),
gimp_display_shell_get_show_grid(),
gimp_display_shell_set_snap_to_grid() and
gimp_display_shell_get_snap_to_grid().
* app/display/gimpdisplayshell-callbacks.c: added call to
gimp_display_shell_draw_grid()
* app/display/gimpdisplayshell.[ch]: added grid member to
_GimpDisplayShellVisibility, added snap_to_grid and grid_dialog
members to _GimpDisplayShell, added
gimp_display_shell_draw_grid(), modified
gimp_display_shell_snap_coords() to use the new
gimp_image_snap_*() functions.
* app/gui/image-menu.c: added grid entries to
image_menu_entries[].
* app/gui/view-commands.[ch]: added
view_configure_grid_cmd_callback(),
view_toggle_grid_cmd_callback() and
view_snap_to_grid_cmd_callback().
* app/gui/Makefile.am
* app/gui/grid-dialog.[ch]: added a grid dialog.
