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.
