	* pango/pango-engines.[ch] pango/pango-engines-private.h:
	Modules now declare a list of scripts that they cover instead of a
	list of code point ranges. Also, there is now a ->covers() virtual
	function that allows a module to decide live whether the font
	covers a particular codepoint; remove old get_coverage() method.

	* pango/pango-fontset.[ch]: Add a foreach() function to
	iterate over all the fonts in a fontset (with a true
	return stopping iteration).

	* pango/pango-context.c: Complete rewrite using script-run
	information to improve language tags. Switch to an approach
	where we handle one run at a time rather than computing
	information for each character individually then later
	breaking the result into runs.

	* pango/pango-fontset.[ch]: Switch over to using
	pango-impl-utils.h.

	* modules/basic/basic-x.c pango/pangox-fontmap.c: Adapt to
	the change from get_coverage => covers.

	* pango/pango-modules.h pango/modules.c: Switch PangoMap
	over to being based on script rather than being based
	on codepoint. Remove the no longer needed pango_map_get_entry().

	* pango/modules.c: Handle new script-based modules.

	* pango/pango-fc-fontmap.c pango/pango-win32-fontmap.c
	pango/pang-fontmap.[ch]: Add a shape_engine_type field
	to PangoFontmapClass, pango_font_map_get_shape_engine_type();
	this allows generic code to find a shaper for a particular
	fontmap.

	* pango/pango-script.[ch]: Add pango_script_get_sample_language(),
	pango_language_includes_script(); functions for determining
	the relationship between scripts and language.

	* tools/gen-script-for-lang.c: Modify to spit out a
	useful table.

	* pango/pango-script-lang-table.h: Version of table
	generated from current fontconfig data.

	* pango/pangox.c: Remove complicated code to compute
	coverages; no longer useful now that we just have
	the basic shaper as a legacy thing.

	* modules/*/*.c: Adapt to identifying shape engines
	by language range.

	* modules/thai/thai-fc.c modules/thai/thai-shaper.[ch]:
	Remove now unused "has_glyph" function and XTIS support.

	* modules/thai/thai-fc.c: Handle non-Thai characters
	as well, since the Thai module now gets spaces,
	punctuation, and so forth.
