2006-10-09  Michael Natterer  <mitch@gimp.org>

	Added message severities and make sure all messages are routed
	through a central function, so redirecting to the error console or
	stderr work again:

	* app/core/core-enums.[ch]: added enum GimpMessageSeverity { INFO,
	WARNING, ERROR }.

	* app/core/gimp.[ch] (gimp_message)
	(gimp_message_valist): added severity parameter. Changed
	"GimpProgress *progress" parameter to "GObject *handler", where
	"handler" can be either a GimpProgress, a GtkWidget or NULL.

	* app/core/gimp-gui.[ch] (gimp_show_message): ditto. Honor
	--console-messages again. Always dispatch to the GUI message
	handler first if it exists.

	* app/gui/gui-message.[ch]: pass severity parameters around.

	(gui_message_error_dialog): if "handler" is a progress, dispatch
	the message to it first. If it is a widget (and *not* a progress),
	use a GtkMessageDialog on top of that widget's toplevel. Fall
	back to the usual GimpErrorDialog otherwise.

	* app/core/gimpprogress.[ch] (gimp_progress_message): added
	severity parameter. Also added boolean return value to the virtual
	function so it can decide to fail if it can't handle the message.

	* app/display/gimpdisplay.c: implement GimpProgress::message() and
	redirect the message to GimpDisplayShell.

	* app/display/gimpdisplayshell-progress.c: implement
	GimpProgress::message() and redirect the message to GimpStatusbar
	if it is not an error and if the status bar is visible.

	* app/display/gimpstatusbar.[ch]: implement GimpProgress::message(),
	but fail on messages that contain a newline. Show the right icons
	for the message severities (work in progress).

	* app/display/gimpdisplayshell.[ch]: removed
	gimp_display_shell_message() and its _valist() variant.

	* app/widgets/gimperrorconsole.[ch]: show the right icons for the
	message severities.

	* app/widgets/gimpthumbbox.c (gimp_thumb_box_progress_message):
	return TRUE to swallow all messages.

	* app/widgets/gimpwidgets-utils.[ch]: removed
	gimp_show_message_dialog(). Added gimp_get_message_stock_id().

	* tools/pdbgen/pdb/gradient.pdb
	* tools/pdbgen/pdb/image.pdb
	* tools/pdbgen/pdb/message.pdb
	* tools/pdbgen/pdb/palette.pdb: added severity parameter to
	gimp_message() calls. Convert all calls to
	gimp_show_message_dialog() and gimp_display_shell_message() to
	gimp_message(). Also converted some more g_message() calls.

	* app/pdb/brush_cmds.c
	* app/pdb/gradient_cmds.c
	* app/pdb/image_cmds.c
	* app/pdb/message_cmds.c
	* app/pdb/palette_cmds.c: regenerated.
