2001-06-18  Michael Natterer  <mitch@gimp.org>

	* app/nav_window.[ch]: major cleanup. After being finished, I
	decided that it needs to be factored out to a widget (see below),
	so like 90% of this file will go away soon.

	* app/apptypes.h: added opaque NavigationDialog typedef.

	* app/gdisplay.[ch]: Added gdisplay_selection_visibility() which
	is called from gdisplays_selection_visibility(). Capitalized the
	SelectionControl enum values. Cleaned up the GDisplay struct and
	it's initialisation while i was on it.

	* app/gimage.c: gimage_size_changed_handler(): removed stuff which
	is now done by GimpImage itself.

	* app/scale.c
	* app/scroll.c: also update the navigation popup, not only the
	dialog.

	* app/selection.[ch]: major indentation & cleanup attack. Maybe
	found the "Selection vanishes" bug (the timeout id was assinged to
	a gint, not a _guint_).

	* app/undo.c: s/gimp_image_size_changed/gimp_viweable_size_changed/

	* app/core/gimpdrawable.c: invalidate the image's preview from our
	"invalidate_preview" implementation. This means that the image's
	preview is invalidated way too often currently, which cries for
	some general freeze/thaw mechanism on the GimpViewable level.
	(Note that previews are rendered in the idle loop, so this is not
	really a major performance impact, it's just ugly).

	* app/core/gimpimage.[ch]: removed the "size_changed" signal...

	* app/core/gimpviewable.[ch]: ...and added it here.

	* app/core/gimplayer.c: invalidate_preview(): always chain up,
	also if it's a floating selection.

	* app/gui/info-dialog.[ch]
	* app/gui/info-window.c: minor cleanups.

	* app/gui/preferences-dialog.c: no need to invalidate the image
	after we have invalidated all it's layers.

	* app/core/gimpimage-mask.c
	* app/gui/commands.c
	* app/tools/gimpeditselectiontool.c
	* app/tools/gimpinktool.c
	* app/tools/gimpmovetool.c
	* app/tools/gimppainttool.c: capitalized the SelectionCommand enum
	values.

	* app/widgets/Makefile.am
	* app/widgets/widgets-types.h
	* app/widgets/gimpnavigationpreview.[ch]: new widget.

	* app/widgets/gimppreview.[ch]: added a non-working
	non-dot-for-dot mode. Added xres/yres params to the
	gimp_preview_calc_size() helper function.

	Cache the "size" value which was passed to the simple function
	variants (gimp_preview_new() and gimp_preview_set_size()) so we
	can re-calculate the preview's extents on the underlying
	viewable's "size_changed" signal and on gimp_preview_set_viewable().

	* app/widgets/gimpdrawablepreview.c
	* app/widgets/gimpimagepreview.c: changed accordingly.
