2001-07-04 Michael Natterer <mitch@gimp.org> * app/core/Makefile.am * app/core/core-types.h * app/core/gimp.[ch]: added an "application object" called Gimp. Currently, it contains the image list, the clipboard, the data factories, the procedural hashtable and the tool info list. It's the toplevel object of the core object system. Finally, creating a Gimp object will return a standalone gimp core engine instance with no other global states/variables involved. * app/app_procs.[ch]: allocate a "Gimp" instance called "the_gimp" :) Removed stuff which is now done by the "Gimp" object. Merged gimp_init() into app_init() because gimp_init() is taken now. * app/context_manager.[ch]: removed stuff done by "Gimp". * app/batch.[ch] * app/gimage.[ch] * app/xcf/xcf-load.[ch] * app/xcf/xcf.[ch] * app/core/gimpedit.[ch] * app/tools/tool_manager.[ch]: pass around an additional "Gimp" argument. * app/pdb/procedural_db.[ch]: pass a "Gimp" pointer as first parameter to all internal procedures and to all procedural_db_* functions. * app/core/gimpcontext.[ch] * app/core/gimpimage.[ch]: added a "Gimp" pointer to the structs. * app/devices.c * app/errors.c * app/file-open.c * app/file-save.c * app/gimphelp.c * app/gimpunit.c * app/image_new.c * app/main.c * app/nav_window.c * app/plug_in.c * app/base/base.c * app/core/gimpdatafactory.c * app/core/gimpimage-duplicate.c * app/core/gimpimage-mask.c * app/core/gimptoolinfo.[ch] * app/gui/brush-select.c * app/gui/convert-dialog.c * app/gui/dialogs-constructors.c * app/gui/edit-commands.c * app/gui/file-open-dialog.c * app/gui/file-save-dialog.c * app/gui/gradient-editor.c * app/gui/gradient-select.c * app/gui/gui.c * app/gui/image-commands.c * app/gui/info-window.c * app/gui/menus.c * app/gui/palette-editor.c * app/gui/palette-import-dialog.c * app/gui/palette-select.c * app/gui/paths-dialog.c * app/gui/pattern-select.c * app/gui/preferences-dialog.c * app/gui/test-commands.c * app/gui/toolbox.c * app/gui/tools-commands.c * app/tools/gimpbezierselecttool.c * app/tools/gimpbucketfilltool.c * app/tools/gimppainttool.h * app/tools/gimptexttool.c * app/tools/gimptransformtool.h * app/widgets/gimpbufferview.c * app/widgets/gimpcontainerview-utils.c * app/widgets/gimpcursor.c * app/widgets/gimpdnd.c * app/widgets/gimpimagedock.c: changed accordingly. Cleaned up lots of includes. Many files still access the global "the_gimp" variable exported by app_procs.h. * tools/pdbgen/app.pl * tools/pdbgen/pdb/brush_select.pdb * tools/pdbgen/pdb/brushes.pdb * tools/pdbgen/pdb/convert.pdb * tools/pdbgen/pdb/edit.pdb * tools/pdbgen/pdb/fileops.pdb * tools/pdbgen/pdb/gradient_select.pdb * tools/pdbgen/pdb/gradients.pdb * tools/pdbgen/pdb/image.pdb * tools/pdbgen/pdb/palette.pdb * tools/pdbgen/pdb/pattern_select.pdb * tools/pdbgen/pdb/patterns.pdb * tools/pdbgen/pdb/procedural_db.pdb: changed accordingly. Don't use "the_gimp" here because all procedures get passed a "Gimp" pointer now. * app/pdb/*: regenerated.
