gimp/app/display/gimpdisplayshell-handlers.c
Michael Natterer 72284d3835 added back the handler which invalidates the display_title on dirty/clean. 
2002-02-15  Michael Natterer  <mitch@gimp.org>

	* app/display/gimpdisplayshell-handlers.c: added back the handler
	which invalidates the display_title on dirty/clean. Removing it
	was simply wrong.

	* app/display/gimpdisplayshell-scale.c: don't call
	gimp_display_shell_update_title() directly but set
	shell->title_dirty to TRUE before calling gdisplays_flush().

	* app/paint/gimppaintcore.[ch]: added gimp_paint_core_constrain()
	which does the "snap to 15 degrees" stuff formerly done in
	GimpPaintTool. Call gimp_brush_select_brush() in
	gimp_paint_core_paint() if paint_state == MOTION, not in several
	other places.  Reordered functions, added some comments and
	documentation.

	* app/paint/gimpairbrush.c
	* app/paint/gimpclone.c
	* app/paint/gimpconvolve.c
	* app/paint/gimpdodgeburn.c
	* app/paint/gimperaser.c
	* app/paint/gimppaintbrush.c
	* app/paint/gimppencil.c
	* app/paint/gimpsmudge.c:
	s/CORE_CAN_HANDLE_CHANGING_BRUSH/CORE_HANDLES_CHANGING_BRUSH/g,
	minor cleanup.

	* app/pdb/pdb-types.h: include "paint/paint-types.h"

	* app/tools/gimppainttool.[ch]: use gimp_paint_core_constrain(),
	removed paint_tool->state because it's not needed any more,
	lots of cleanup.

	* tools/pdbgen/app.pl: another eeky special case for "paint/".

	* tools/pdbgen/pdb/paint_tools.pdb: include stuff from "paint/",
	not "tools/".

	* app/pdb/paint_tools_cmds.c: regenerated.
