Michael Natterer 5e17408c84 Re-enabled the display filters. They work exactly the same way as before
2002-03-14  Michael Natterer  <mitch@gimp.org>

	Re-enabled the display filters. They work exactly the same way
	as before except for the color_area pseudo-display. More stuff
	to come...

	* app/display/Makefile.am: build them again.

	* app/display/gimpdisplayshell-filter-dialog.[ch]
	* app/display/gimpdisplayshell-filter.[ch]: changed to the new
	namespace, work on GimpDisplayShell instead of GimpDisplay.

	* app/display/gimpdisplayshell-render.c
	* app/display/gimpdisplayshell.[ch]: changed accordingly.

	* app/gui/dialogs-constructors.c: enabled the dialog constructor.

	* app/gui/gui.c: call the init() function.

	* app/gui/menus.c: enabled the menu entry, but moved it to
	<Image>/View. Moved "Undo History..." to <Image>/Image.

	* modules/Makefile.am: build and install the modules.

	* modules/cdisplay_gamma.c
	* modules/cdisplay_highcontrast.c: made them compile with minimal
	changes.

	Unrelated:

	* app/undo_history.c: connect to the image's "disconnect", not
	"destroy" signal.

	* app/tools/gimpselectiontool.c: mask out the irrelevant parts of
	the "state" passed to the modifier_key() func, so tool_options
	button toggling works with other modifiers (e.g. num_lock)
	pressed.
