These changes enable help support for 3rd party plug-ins which
install their help files outside GIMP's main help dir.
Instead of calling gimp_help(), gimp_plugin_help_func() etc.,
all help callbacks now have to call gimp_standard_help_func()
which has different implementations in the app and in libgimp.
There is a new function gimp_plugin_help_register() which can
be called during plug-in query. plug_in.c keeps a list of
executable_name/help_path pairs. Plug-ins have to pass their
exec. name to gimp_help() which uses the list to find the plug-in's
help directory.
* app/gimphelp.[ch]: gimp_help() now takes a help_path parameter.
help_path == NULL means the standard help directory. Various
changes to pass the help_path to the help browser.
* app/gimprc.c: save the plug-in's help_path in the pluginrc file.
* app/menus.c: ugly hack to enable help_paths in the "F1" callback.
* app/plug_in.[ch]: many help_path related changes. Use g_basename()
instead of strrchr(str,G_DIR_SEPARATOR), cosmetic cleanups.
* app/internal_procs.c
* app/gimphelp_cmds.c
* tools/pdbgen/pdb/gimphelp.pdb: new procedure
gimp_plugin_help_register(). gimp_help() takes a second parameter
which is the executable name (not the help_path).
* app/color_notebook.c
* app/commands.c
* app/lc_dialog.c
* app/preferences_dialog.c
* app/tools.c: call gimp_standard_help_func() instead of gimp_help().
* libgimp/gimp.c: new function gimp_get_progname() which returns
the full path of the plug-in's executable.
* libgimp/gimp.h: export the new function,
removed gimp_plugin_help_func(), gimp_help() takes the executable
name as second parameter.
* libgimp/gimpcompat.h: added gimp_plugin_help_func().
* libgimp/gimphelp.c: a wrapper for gimp_plugin_help_register(),
changed the calls to gimp_help.
* libgimp/gimphelpui.[ch]: call gimp_standard_help_func() instead
of gimp_help().
* plug-ins/helpbrowser/helpbrowser.c: now called with an additional
help_path parameter. Various changes to enable
help_path != gimp_standard_help_path.
Unrelated stuff:
* app/batch.h: added missing GPL header.
* app/gimpunit.c: had a LGPL header, merged some fprintf's into
one call.
* app/procedural_db.[ch]: cosmetic: g* types, s/g_malloc/g_new/,
prototypes, indentation.
* app/resize.c: use less packing widgets. didn't find the "offset"
redraw bug :(
