	Be more strict about what is considered a valid region with
	partial struts.  Fixes #322070.

	* src/boxes.[ch]:
	(meta_rectangle_expand_region_conditionally):
	new function behaving like meta_rectangle_expand_region() but
	which only does so when the width and height of the rectangles
	meet a certain threshold

	(replace_rect_with_list):
	Remove a compiling warning

	* src/constraints.c:
	(constrain_partially_onscreen):
	provide minimum thresholds in each direction for the size of the
	rectangles to avoid cases where only a single pixel thick layer of
	a window might be showing
