When handling overstrikes, try to guess a bit better how overstrike glyphs

	* modules/basic/basic.c (basic_engine_shape): When
	handling overstrikes, try to guess a bit better
	how overstrike glyphs are positioned in the font.
	(Now works with more of glyphs from clearlyu, though
	not the Hebrew accents in that font)

	* examples/HELLO.utf8: Insert tab characters to
	keep the columns in the right order for either
	global direction. Insert left-to-right marks in
	a few places to keep leading and trailing punctuation
	in the right place.

	* modules/basic/basic.c (basic_engine_shape): Don't
	show RLM and LRM

	* pango/glyphstring.c (pango_glyph_string_extents): Use
	the logical width set in the glyph string rather than
	that from the font's metrics.

	* pango/pangox.c (pango_x_render): Treat glyph index
	0 as special - representing invisible, 0 size
	character. We need this sometimes, and it is
	easier and faster to have this special case
	than to shape a space.

	* pango/pango-context.c (pango_itemize): Put
	tabs into separate items. (Sort of lame hack,
	we do this to make line breaking with tab
	handling simpler)

	* examples/viewer.c (checkbutton_toggled): Notify
	all the layouts that the context has changed so
	the RTL base dir change actually takes effect.
