	* app/core/gimpimage.[ch]: added new signals "sample-point-added"
	and "sample-point-removed" and public functions to emit them.

	* app/core/gimpimage-sample-points.c (gimp_image_add_sample_point)
	(gimp_image_remove_sample_point): emit them accordingly.

	* app/core/gimpimage-undo-push.c (undo_pop_image_sample_point):
	ditto.

	(undo_pop_image_guide)
	(undo_pop_image_sample_point): added comments why we add/remove
	stuff manually instead of using the GimpImage APIs.

	* app/widgets/Makefile.am
	* app/widgets/widgets-types.h
	* app/widgets/gimpcursorview.[ch]
	* app/widgets/gimpsamplepointeditor.[ch]: new widgets.
	GimpCursorView is a replacement for the info window's "Cursor"
	page, GimpSamplePointEditor is a view on an image's sample points.
	The sample point editor does nothing yet except keeping a 2x2 grid
	of GimpColorFrames. Addresses bug #137776.

	* app/dialogs/dialogs.c
	* app/dialogs/dialogs-constructors.[ch]: register the new widgets
	as dockable dialogs.

	* app/actions/dialogs-actions.c (dialogs_dockable_actions)
	* menus/dialogs-menuitems.xml: added actions and menu items for
	the new dialogs.

	* app/display/gimpdisplayshell-cursor.c
	(gimp_display_shell_update_cursor)
	(gimp_display_shell_clear_cursor): update the new cursor view.

	* app/widgets/gimphelp-ids.h: help IDs for the new dialogs.

	* app/widgets/widgets-enums.[ch] (enum GimpColorFrameMode):
	changed description "Pixel values" to "Pixel" because the former
	was too long.
