Updates from #320666:
* pango/Makefile.am: Remove pango-easy-scripts-table.h.
* pango/pango-easy-scripts-table.h: Removed. The "easy" table goes
into pango-scripts-table.h too.
* pango/pango-script-table.h: Include "easy" table.
* pango/pango-script.c: Change gunichar->script last_index caching
mechanism. The caching is simply done by making int mid in the
bsearch static.
* tools/Makefile.am: Remove gen-easy-scripts-table.c.
* tools/gen-easy-scripts-table.c: Removed. The "easy" table is
generated in gen-scripts-table.pl too.
* tools/gen-script-table.h: Generate "easy" table.

2005-11-07 Federico Mena Quintero <federico@ximian.com>
Fixes bug #320666:
Instead of doing a bsearch() for every gunichar to map it to a
PangoScript, use a precomputed table for the first 8192 code
points. Also, remember the last script that we computed on each
invocation; this will also help CJK and the other scripts above
U+2000.
This table also holds information on whether the characters in it
are paired characters. We can use this to avoid doing the
expensive get_pair_index() call most of the time.
Many thanks to Matthias Clasen for his suggestions for this patch.
* tools/gen-easy-scripts-table.c: New program to generate
pango_easy_scripts_table.
* tools/Makefile.am: Build gen-easy-scripts-table.
* pango/pango-easy-scripts-table.h: New file with a mapping of the
first 8192 Unicode characters to their corresponding scripts. The
table also says whether each character has a paired char or not.
* pango/Makefile.am (libpango_1_0_la_SOURCES): Add pango-easy-scripts-table.h.
* pango/pango-script-table.h: Remove everything below U+2000, and
add a note to that effect.
* pango/pango-script.c (pango_script_for_unichar_with_last_index):
New function. This is the old pango_script_for_unichar(), but it
lets the caller keep around the computed index in
pango_script_table. This works under the assumption that a
character is likely to be in the same script block as the
preceding character in a string.
(pango_script_for_unichar): First, do a quick check against the
pango_easy_scripts_table. Then, do the expensive check with
pango_script_for_unichar_with_last_index().
(pango_script_iter_next): If the character is within the easy
script range, find out if it is a paired character by using
PANGO_PAIRED_CHAR_FLAG.
(struct _PangoScriptIter): Add a last_index_for_script_lookup
field. We use this to maintain the last-lookup index from
pango_script_for_unichar_with_last_index().
(pango_script_iter_next): If the character is not within the easy
script range, use pango_script_for_unichar_with_last_index(), and
store the index in the last_index_for_script_lookup field of the
PangoScriptIter.

Tue Sep 23 18:03:57 2003 Owen Taylor <otaylor@redhat.com>
* 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.

libpangox.
Tue May 2 22:59:52 2000 Owen Taylor <otaylor@redhat.com>
* modules/basic/basic.c: Get rid of link list of masks
in cache structure in favor of an array. (This is
easy to do now since we already have linear indices
for the masks from the new table format.)
* pango/modules.c pango/pango-context.c pango/pangox.c:
Modify _pango_find_map() to take quarks for the
engine type and render type instead of strings.
Get rid of the map hash table in favor of a GList
with the most recently used map at the beginning.
* pango/modules.[ch] pango/pango-context.c pango/pangox.c:
Add some utility functions for getting the engine
for a particular character in a map. Using modules.c
knowledge of map structure, this allows us to save
a bunch of useless strcmps.
* pango/pango-context.c (add_engines): Remove unused
lookup of shape mask.
* modules/basic/tables-{small,big}.i modules/basic/basic.c
tools/compress-table.pl: Reencode mask table to avoid binary
searches and save a bit of space.
* modules/basic/basic.c (find_converter): Get rid
of gratuitous use of hash tables for looking up
iconv converters.
* modules/basic/tables-{small,big}.i modules/basic/basic.c:
Use conv_ucs4 instead of conv_8bit for latin-1.

just add up the widths from shaping.
