	* gimprc.in: comment typo fix, plus add %D* to default
	    image-title-format string, so people get a '*' in the titlebar
	    if their image is dirty.
	* app/fileops.c: initialise filename before using it.
	* app/gdisplay.c: empty parameter list () is K&R - should be
	    stronger (void) in ANSI C.
	* app/gimpdrawable.c: gimp_drawable_{dirty,clean} functions
	    removed - no one uses them anyway.  Parasite undo type is
	    proper parasite undo type, not MISC_UNDO.
	* app/gimpdrawableP.h: drawable dirty bit removed.
	* app/gimpimage.c: don't change the resolution if there's no
	    difference from the old one.  Call gdisplay_shrink_wrap() to
	    re-calculate scale factors and refresh the display on
	    resolution change.  Layer undo doesn't have sub-types
	    anymore, uses main UndoType instead.
	* app/layer.h: Remove LayerUndoType
	* app/qmask.c: fix qmask undo so it actually works.
	* app/undo.h: new types for undo_push_layer{,_mask} and
	    undo_push_qmask.
	* app/undo.c: change way group boundaries are represented:
	    each Undo has a group_boundary boolean set to TRUE if this is
	    the start or the end of a group, and the type of the Undo is
	    the group's type.  Within a group, each Undo keeps its own
	    type.  This allows pop funcs and free funcs to do
	    type-specific things (eg needed by layer and channel stuff).
	    Don't maintain per-drawable dirty flags anymore.   Floating
	    sel to layer and layer rename now uses meaningful undo types.
	* app/undo_types.h: more specific undo types:
	    LAYER_{ADD,REMOVE}_UNDO, LAYER_MASK_{ADD,REMOVE}_UNDO,
	    LAYER_RENAME_UNDO, and PARASITE_{ATTACH,DETACH}_UNDO.
	* app/undo_history.c: oops - undo stack was being placed into gtk
	    list in wrong order.
	* app/edit_selection.c: push more descriptive LAYER_DISPLACE_UNDO
	    rather than MISC_UNDO.
	* app/layers_dialog.c: better tagging of undo types
