	* app/Makefile.am
	* app/gimphelp.[ch]: removed...

	* app/widgets/Makefile.am
	* app/widgets/gimphelp.[ch]: ...and added here.

	* app/widgets/widgets-enums.[ch]: added GimpHelpBrowserType here
	as registered enum. Added an evil hack with GimpCursorType so
	app/config/gimpguiconfig.h can include this file.

	* app/widgets/gimpcursor.c: added an assertion because of the
	changed GimpCursorType.

	* app/config/gimpguiconfig.[ch]: added a property for the help
	browser type.

	* app/gimprc.c
	* app/libgimp_glue.c
	* app/gui/preferences-dialog.c
	* tools/pdbgen/pdb/help.pdb

	* app/pdb/help_cmds.c: regenerated.

	Some nav_window cleanup before chopping:

	* app/nav_window.[ch]: removed the old preview code and use
	GimpNavigationPreviews only. Namespaceified all functions. Speak
	in terms of GimpDisplayShell, not GimpDisplay. Lots of internal
	cleanup.

	* app/gui/gui-types.h: removed NadiagtionDialog here...

	* app/display/display-types.h: ...and added it here.

	* app/display/gimpdisplayshell-callbacks.[ch]: added a callback
	for the navigation button and call nav_window_show_popup() from there.

	* app/display/gimpdisplayshell.c: free shell->nav_dialog
	unconditionally, connect to the new callback.

	* app/display/gimpdisplayshell-scale.c
	* app/display/gimpdisplayshell-scroll.c
	* app/gui/view-commands.c: changed accordingly.

	* app/widgets/gimppreview.c (gimp_preview_set_viewable): the
	assertion introduced recently was too tight, breaking
	GimpNavigationPreview. Changed it to do an "is a" check, not exact
	preview type matching.

	* app/widgets/gimpimagepreview.c: added quick-hack support for
	xres != yres.

	* app/widgets/gimpnavigationpreview.[ch]: made
	gimp_navigation_preview_grab_pointer() public so the nav_window
	can call it.

	Unrelated:

	* app/display/gimpdisplay.c: removed the gui/ dependency from this
	file by removing info_window stuff.

	* app/display/gimpdisplayshell.c (gimp_display_shell_flush): update
	the info_window here.

	* app/gui/dialogs-constructors.c (dialogs_indexed_palette_new): call
	gimp_dockable_set_context() like all other constructors.

	* app/undo.c
	* app/paint/gimppaintcore.h: some more include cleanup.
