	* cut-n-paste-code/widgets/gimphwrapbox/gtkwrapbox.h:
	Copied and pasted the wrapping hbox from the Gimp.
	I made a few modifications, including some resizing requests,
	when the chosen size is not the right one for the actual
	space available.  Sizing wrapping boxes is a tricky problem
	with gtk, because they have nonstandard sizing requests
	(they can request x or y or z) and my solution is probably
	not optimal, since some of the sizing adjustments are visible
	on screen.  However, a better fix is a lot more time consuming,
	and should probably wait for past 1.0.

	(unattach_criterion_from_search_bar),
	(load_find_them_pixmap_widget), (more_options_callback),
	(fewer_options_callback), (update_options_buttons_state):
	* src/nautilus-complex-search-bar.h:
	Changed the criteria layout to be in a vbox instead of a table,
	so that we can insert wrapping hboxes.  Added a new function
	that will effectively resize the complex search bar, and we call
	it at appropriate points. Switched the packing order of the
	buttons, since the wrap box has only one packing function, and it is
	a pack_start, rather than a pack_end function

	* src/nautilus-search-bar-criterion-private.h:
	* src/nautilus-search-bar-criterion.c: (queue_bar_resize_callback),
	(nautilus_search_bar_criterion_new_from_values),

	(nautilus_search_bar_criterion_update_valid_criteria_choices),
	(hide_date_widget), (show_date_widget), (make_emblem_value_menu):
	Put the criteria into wrapping boxes as part of their creation, and
	trigger a resize of the complex search bar when the wrapping box
	complains about its allocated size.
