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 :(

*app/docindex.c
Used feof(fp) as a hardware independent indicator, replacing
constructs comparing EOF (-1) to integers that once were unsigned
characters. Puts an end to infinite looping at line 239 giving rise to
#11578. See bug report; closes 11578.

* plug-ins/webbrowser/web-browser.scm: added links to
Carey Bunks's "Gimp-Savvy" and "Grokking the GIMP" resources.
* libgimp/gimpwidgets.[ch]: use unsigned integers for the
memsize_entry. Added gimp_uint_adjustment_update().
* gimprc.[ch]
* preferences_dialog.c: use unsigned integers for memsizes
(tile_cache_size and max_new_image_size). Allows to set those
values up to 4GB. Fixes bug #11053.

* app/transform_core.c (transform_core_cut): when transforming
a selection in an indexed image, we used to create an indexed
tile_buffer. This gives strange (black) results later when we
use layer_new_from_tiles() since that function assumes that a
TileManager is always RGB or GRAY. Eeek!!
Instead of fixing it correctly by changing the TileManager
struct, I've unset the keep_indexed flag when calling
gimage_mask_extract(), so whatever layer_new_from_tiles()
assumes becomes true. Fixes bug #10762.

* app/plug_in.c: be a bit more verbose in the "Plug-In crashed"
message: Warn the user that Gimp's internal state may be messed
up and that the safe way is to restart Gimp.
Unified all plug-in error messages.
* libgimp/gimp.c: also changed to messages that the Gimp is using
a newer/older wire protocol than the plug-in.
2000-05-16 Michael Natterer <mitch@gimp.org>
* app/commands.c
* app/layers_dialog.c
* app/resize.c: set the scale/resize dialog insensitive before
scaling/resizing to keep users from pressing "OK" again.
Fixes#10656.

* libgimp/gimpenv.c (gimp_path_parse)
* app/gimprc.c (transform_path): Don't try to handle tilde (~) at
all on Windows. The tilde is used when mangling long file names
into 8.3 form, and some people have a HOME environment variable
that contains this kind of 8.3 path with a tilde. This causes
interesting effects if we expand a tilde in some gimprc variable
with $HOME, which contains a tilde, which we expand with $HOME,
etc.

* plug-ins/common/gpb.c (gih_save_dialog): Fix typo introduced
when gimp_spin_button_new() was taken into use. Now you can adjust
the cell height again.

After a weekend of extensive mail exchange with the signal crew,
we finally found that #2742 is not a Gimp bug but a real OSF/1
bug. OSF/1 does _not_ reliably restart read() and write() calls
on certain slow devices (pipes).
* libgimp/gimpwire.[ch]: guard all read/write calls on the wire
with loops checking for EINTR. This has to be done "manually"
as glib's GIOChannels return G_IO_ERROR_UNKNOWN on the occurence
of EINTR (which is a bug, too).
s/int/gboolean and minor cleanups while I was on it (not changing
any logic).
This fix depends on the current (broken) state of the GIOChannel
implementation and is scheduled for removal as soon as glib
behaves nicely here.
Left SA_RESTART there for the moment in app/main.c. See it as
defensive programming or just my fear to change two #2742-related
places at the same time. We might choose to remove SA_RESTART
later. Many thanks again to Austin, Garry and Tim.

* gimpdrawable.c: enabled the (commented out) signal
"invalidate_preview".
* app/layers_dialog.c: connect to the "invalidate_preview"
signal to catch changes that need to be shown in the layer
previews. Synthetize an expose event when a layer changes.
Expose events are optimzed away by GTK+ if the widget is not
visible. Therefore, previews not visible in the layers_dialog
are not redrawn when they invalidate. Later the preview gets
validated by the image_preview in lc_dialog but is never
propagated to the layer_pixmap. We work around this by using an
additional flag "layer_pixmap_valid" so that the pixmap gets
updated once the preview scrolls into sight.
Fixes bugs #10549, #10300 and #8787.
* app/channel.[ch]
* app/layer.[ch]: code review and indentation
