gimp/plug-ins/script-fu/script-fu.c
Michael Natterer 22371de3e7 added a note about apptype.h and about not including headers in headers. 
2001-02-14  Michael Natterer  <mitch@gimp.org>

	* HACKING: added a note about apptype.h and about not including
	headers in headers.

	* app/apptypes.h: added GimpTool and BitmapCursor.

	* app/cursorutil.h
	* app/devices.h
	* app/draw_core.h
	* app/tools/color_picker.h
	* app/tools/tool.h
	* app/tools/tool_options.h
	* app/gimpcontext.h: removed includes of "tools/tool.h"

	* app/gimprc.[ch]: indentadion cleanup, added
	"module_db_load_inhibit".

	* app/module_db.c: removed the above variable here.

	* app/gimpdata.[ch]: added a vitrual "duplicate" method.

	* app/gimpbrush.[ch]
	* app/gimpbrushgenerated.[ch]
	* app/gimpbrushpipe.[ch]
	* app/gimpgradient.[ch]
	* app/gimppalette.[ch]
	* app/gimppattern.[ch]: all "load", "new" and "get_standard"
	functions return a GimpData pointer now.

	* app/gimpdatafactory.[ch]: made some stuff const.

	* app/gimpdatafactoryview.c: activate the "duplicate" button and
	set the initial button sensitivity correctly.

	* app/brush_select.c
	* app/gradient_select.c
	* app/pattern_select.c: use the new GimpDataFactoryView.

	* libgimp/Makefile.am: grouped the file to sort out what _may_
	go to subdirs or separate libs.

	* libgimp/gimpenv.[ch]: added many "const".

	* app/app_procs.c
	* app/brush_edit.c
	* app/gimpcontext.c
	* app/gimpdnd.c
	* app/gradient_editor.c
	* app/palette.c
	* app/palette_import.c
	* app/user_install.c: many related changes.

	* libgimpmath/gimpmathtypes.h
	* libgimpmath/gimpvector.[ch]: minor cleanups.

	* plug-ins/script-fu/script-fu.c: gimp_data_directory() is const now.
