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.
