gimp/app/gui/layers-commands.c
Michael Natterer 1329e016d2 app/core/gimpimage-mask.[ch] (gimp_image_mask_translate) added "gboolean 
2003-03-18  Michael Natterer  <mitch@gimp.org>

	* app/core/gimpimage-mask.[ch] (gimp_image_mask_translate)
	* app/core/gimplayer.[ch] (gimp_layer_translate): added
	"gboolean push_undo" parameters.

	* app/core/gimpimage-crop.c
	* app/core/gimpimage-resize.c
	* app/display/gimpdisplayshell-dnd.c
	* app/gui/layers-commands.c
	* app/widgets/gimptoolbox.c
	* tools/pdbgen/pdb/layer.pdb
	* tools/pdbgen/pdb/selection.pdb: changed accordingly.

	* app/pdb/layer_cmds.c
	* app/pdb/selection_cmds.c: regenerated.

	* app/core/gimpimage-undo-push.c (undo_pop_layer_displace): call
	gimp_layer_translate() with "push_undo == FALSE" instead of
	duplicating gimp_layer_translate()'s code. Use GimpItemUndo for
	GIMP_UNDO_MASK.

	* app/tools/gimpeditselectiontool.c
	(gimp_edit_selection_tool_cursor_key): check if the top undo on
	the stack is of exactly the same type as the undo we would push
	and just don't push it then (compresses layer translate undos and
	fixes bug #86362). Changed stuff work with CAPS_LOCK or other
	modifiers pressed.
