2001-07-11 Michael Natterer <mitch@gimp.org> * app/Makefile.am * app/gimpunit.c * app/unitrc.h: removed... * app/core/Makefile.am * app/core/gimpunit.[ch]: ...re-added here. * app/core/gimp.[ch]: added the image and drawable hash tables, next_image_ID, next_guide_ID and next_drawable_ID, added a GimpCoreConfig pointer which is now initalized dynamically. * app/core/gimpcoreconfig.[ch]: don't provide a global core_config variable any more (need to access gimp->config now). * app/gdisplay.[ch] * app/core/gimpdrawable.[ch] * app/core/gimpimage.[ch]: removed all global variables from gimpimage.c and gimpdrawable.c, pass a Gimp* to all *_get_by_ID() functions. * tools/pdbgen/app.pl: pass Gimp* to all _get_by_ID() functions. * app/app_procs.c * app/file-open.c * app/file-save.c * app/gimprc.c * app/libgimp_glue.c * app/module_db.c * app/plug_in.c * app/undo.c * app/user_install.c * app/core/core-types.h * app/core/gimpcontext.c * app/core/gimpimage-crop.c * app/core/gimpimage-new.c * app/core/gimpparasite.c * app/gui/file-new-dialog.c * app/gui/file-open-dialog.c * app/gui/info-window.c * app/gui/preferences-dialog.c * app/gui/resize-dialog.c * app/xcf/xcf-load.c * app/xcf/xcf-save.c * app/xcf/xcf.c * app/widgets/gimpdnd.c * app/pdb/channel_cmds.c * app/pdb/color_cmds.c * app/pdb/convert_cmds.c * app/pdb/display_cmds.c * app/pdb/drawable_cmds.c * app/pdb/edit_cmds.c * app/pdb/fileops_cmds.c * app/pdb/floating_sel_cmds.c * app/pdb/guides_cmds.c * app/pdb/image_cmds.c * app/pdb/layer_cmds.c * app/pdb/parasite_cmds.c * app/pdb/paths_cmds.c * app/pdb/selection_cmds.c * app/pdb/text_tool_cmds.c * app/pdb/tools_cmds.c * app/pdb/undo_cmds.c * app/pdb/unit_cmds.c * tools/pdbgen/pdb/image.pdb * tools/pdbgen/pdb/unit.pdb: changed accordingly.
