* 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.

pango/modules.c pango/break.c pango/pango-context.c
pango/pango-layout.c pango/pango-modules.h
pango/querymodules.c pango/shape.c: Make
PangoEngine{,Lang,Shape} GObjects, and use a
GTypeModule-based module-loading system closely based
on the one used for GtkIMContext and GtkThemeEngine.
* pango/pango-impl-utils.h: OK, I'm tired of typing
in get_type() functions.
* pango/pango-script.[ch] pango/pango-script-table.h
tests/testscript.c tools/gen-script-table.pl: Add port
of script-range code from ICU in preparation for future
use. (#91542)
* tools/gen-script-for-lang.c: Utility program to determine
the script for each fontconfig .orth file.
