gimp/app/core/gimpimage-guides.h
Michael Natterer f13f80f04a added "position" and "push_undo" parameters to gimp_image_add_[vh]guide().
2003-03-28  Michael Natterer  <mitch@gimp.org>

	* app/core/gimpimage-guides.[ch]: added "position" and "push_undo"
	parameters to gimp_image_add_[vh]guide(). Start with a refcount
	of 1, not 0 (EEK). Added gimp_image_guide_[un]ref(). Added
	"position" parameter to gimp_image_add_guide(). Added new
	function gimp_image_move_guide(). All functions push guide
	undos correctly and call gimp_image_update_guide() so this
	doesn't need to be done by callers.

	* app/core/gimpimage-crop.c
	* app/core/gimpimage-duplicate.c
	* app/core/gimpimage-resize.c
	* app/core/gimpimage-undo-push.c
	* app/core/gimpimage.c
	* app/tools/gimpmeasuretool.c
	* app/xcf/xcf-load.c
	* tools/pdbgen/pdb/guides.pdb: greatly simplyfied all places which
	modify guides: don't fiddle with undo and guide properties
	manually but simply use the API provided.

	* app/tools/gimpmovetool.[ch]: ditto. Changed everything to
	create/move the guide on button_release, not button_press. Enable
	canceling the operation by clicking button3 before releasing
	button1. Keep the guide drawn at its old position until the move
	is finished (fixes bug #75349 and bug #109267).

	* app/pdb/guides_cmds.c: regenerated.
