2001-05-15 Michael Natterer <mitch@gimp.org> * configure.in: new directory app/base/ * app/Makefile.am * app/boundary.[ch] * app/brush_scale.[ch] * app/gimpchecks.h * app/gimplut.[ch] * app/pixel_processor.[ch] * app/pixel_region.[ch] * app/pixel_surround.[ch] * app/temp_buf.[ch] * app/tile.[ch] * app/tile_cache.[ch] * app/tile_manager.[ch] * app/tile_manager_pvt.h * app/tile_pvt.h * app/tile_swap.[ch]: moved to base/ * app/base/Makefile.am * app/base/base-types.h * app/base/*: new directory for the sub-object pixel maniplation and storage stuff. Does not include Gtk+ or anything outside base/. Did some cleanup in all files. * app/appenums.h * app/apptypes.h * app/core/gimpimage.h: removed types which are now in base/base-types.h. * app/base/base-config.[ch] * app/gimprc.[ch]: put the config variables for base/ to their own file so base/ doesn not have to include gimprc.h (does not yet work, i.e. the variables are un-configurable right now) * app/main.c: set a log handler for "Gimp-Base". * app/paint-funcs/Makefile.am * app/paint-funcs/paint-funcs.[ch]: removed the color hash which maps RGB to color indices because it's a totally standalone system which has nothing to do with the paint-funcs and introduced a GimpImage dependency. paint-funcs/ should be considered on the same sub-object (glib-only) level as base/, only in a different directory. * app/core/Makefile.am * app/core/gimpimage-colorhash.[ch]: put the color hash here. * app/gimage.c: don't invalidate the color hash here... * app/core/gimpimage.c: ... but in the colormap_changed() default inplementation. Initialize the hash in class_init(). * tools/pdbgen/Makefile.am: scan app/base/base-types.h for enums. * tools/pdbgen/enums.pl: regenerated. * app/[lots] * app/core/[of] * app/gui/[files] * app/pdb/[all] * app/tools/[over] * app/widgets/[the] * tools/pdbgen/pdb/[place]: changed #includes accordingly. And use base_config->value instead of the stuff from gimprc.h.
