Changed the semantics of GIMP_EXTENSION and (to some extent)
of GIMP_PLUGIN:
The old meaning of EXTENSION was "I live in the toolbox" and
PLUGIN meant "I take RUN-MODE,IMAGE,DRAWABLE args (but only if I
am invoked interactively)". This is completely useless, since
living in the toolbox means having "<Toolbox>" in the menu_path
and taking RUN-MODE,IMAGE,DRAWABLE means just that, regardless of
what type of procedure we are.
The new meaning of GIMP_PLUGIN is just "I am an ordinary procedure,
I am invoked, do my job and finish", while GIMP_EXTENSION means
"I will install temporary procedures and I will keep running to
keep them available".
(A GIMP_EXTENSION *must* call gimp_extension_ack() now to tell the
core that it's ready to run, or the core will block waiting for
the message !!!).
* configure.in: bumped version number to 1.3.16.
* libgimpbase/gimpprotocol.h: increased protocol version number so
old extensions will refuse to load.
* app/gui/plug-in-commands.c (plug_in_run_cmd_callback): don't
blindly pass RUN-MODE,IMAGE,DRAWABLE to GIMP_PLUGIN procedures but
look at their parameters and pass them either RUN-MODE, or
RUN-MODE,IMAGE, or RUN-MODE,IMAGE,DRAWABLE.
* app/pdb/procedural_db.c: cleaned up, better error reporting,
replaced an impossible error message by g_return_if_fail()
* app/plug-in/plug-in-message.c (plug_in_handle_proc_install):
better error messages.
* app/plug-in/plug-in-params.c: allocate parameter arrays using
g_new0() so we don't have to worry about uninitialized stuff
later.
* app/plug-in/plug-in-run.c (plug_in_run): wait for
gimp_extension_ack() installation confirmation for ALL extensions,
not just for automatically started ones.
* app/plug-in/plug-ins.c: cleanup.
* libgimp/gimp.[ch]: cleaned up and API-documented massively. Made
all magic values given in the GPConfig message static and added
accessor functions for them. Added gimp_tile_width()/height().
Added new function gimp_extension_enable() which turns on
asynchronous processing of temp_proc run requests without having
to enter an endless gimp_extension_process() loop. Moved all
private functions to the end of the file. Added tons of
g_return_if_fail() all over the place. Call gimp_run_procedure2()
from gimp_run_procedure() instead of duplicating the
code. Indentation, spacing, stuff...
* libgimp/gimptile.[ch]: removed gimp_tile_width()/height().
* libgimp/gimpdrawable.c
* libgimp/gimppixelrgn.c
* libgimp/gimptile.c: use the gimp_tile_width()/height() accessor
functions.
* libgimp/gimp.def: added gimp_extension_enable.
* libgimp/gimpmenu.c: removed evil code which connected to
_readchannel manually and use gimp_extension_enable() for watching
temp_procs.
* plug-ins/helpbrowser/helpbrowser.c: removed the same evil code
here and call gimp_extension_enable(). Call gimp_extension_ack()
to let the core know that the temp_proc is installed.
* plug-ins/script-fu/script-fu.c: made all procedures except the
permanently running "extension_script_fu" ordinary GIMP_PLUGIN
procedures.
* plug-ins/common/curve_bend.c
* plug-ins/common/plugindetails.c
* plug-ins/common/screenshot.c
* plug-ins/common/uniteditor.c
* plug-ins/common/winclipboard.c
* plug-ins/dbbrowser/dbbrowser.c
* plug-ins/gfli/gfli.c
* plug-ins/twain/twain.c
* plug-ins/webbrowser/webbrowser.c
* plug-ins/winsnap/winsnap.c: made them all ordinary GIMP_PLUGIN
procedures and renamed them from "extension_*" to "plug_in_*".
Random cleanups.
* app/widgets/gimphelp.c
* plug-ins/maze/maze_face.c: call "plug_in_web_browser" now.
