2003-02-12 Michael Natterer <mitch@gimp.org> Moved the undo system to the core: Keep GimpUndoStack objects as undo and redo stack. Use GimpUndo objects as members of the stacks. GimpUndoStack is derived from GimpUndo and keeps undo groups, so undo group handling is much simpler than before (the whole group is just a single GimpUndo object on the stack and not everything between group boundary markers). * app/Makefile.am * app/undo_types.h: removed. * app/config/gimpcoreconfig.[ch]: added "gulong undo_size". * app/config/gimprc-blurbs.h: and its blurb. * app/core/core-enums.[ch]: added GimpUndoMode and GimpUndoType. * app/core/core-types.h: removed UndoType, added GimpUndoAccumulator, GimpUndoPopFunc and GimpUndoFreeFunc. * app/core/gimpundo.[ch]: do everything the old "Undo" struct did. Removed the virtual push() function and added free(). * app/core/gimpundostack.[ch]: keeps the new undo/redo stacks and also acts as undo group. * app/core/gimpimage-undo.[ch]: moved the undo apparatus here. * app/core/gimpimage.[ch]: removed the old stuff. * app/core/gimpmarshal.list: added marshaller needed for GimpUndo. * app/undo.[ch]: removed the whole undo mechanism. Only the actual undo pushing functions are left. * app/undo_history.c * app/gui/edit-commands.c * app/gui/file-commands.c * app/gui/image-menu.c * app/gui/preferences-dialog.c * app/tools/gimpeditselectiontool.c: changed accordingly.
