2001-02-11 Michael Natterer <mitch@gimp.org> * app/apptypes.h: added the datafile loader_func typedefs. * app/datafiles.h: removed from here. * app/gimpcontainer.[ch]: emit "freeze" and "thaw" signals to get rid of those blah_select_[freeze|thaw]_all() stuff. * app/gimpdatalist.[ch]: new function gimp_data_list_load() which takes a va_list of GimpDataObjectLoaderFuncs and file extensions and is almost a replacement for the four files below. * app/brushes.c * app/gradients.c * app/palettes.c * app/patterns.c: very simple now. It may be worth thinking about making all GimpData subclasses managed by a descriptive array in the context_manager.
