	remaining string is a syllable.

	Bug 388581 - Every last Hangul syllable is decomposed to jamos.

	remaining string is a syllable.

	* pango/pangofc-fontmap.c (pango_fc_face_describe):
	Call FcConfigSubstitute and FcDefaultSubstitute before calling

2006-12-19  Behdad Esfahbod  <[e-mail]>

	Bug 326099 – Setting width, indentation and ellipsizing doesn't work
	as I would expect

	* pango/ellipsize.c (_pango_layout_line_ellipsize): Account for
	indentation when deciding what width to ellipsize for.

	* pango/pango-layout.c (get_alignment): Don't bother about
	conditioning on the line direction for center alignment.

	* modules/hangul/hangul-defs.h:

	(hangul_engine_shape): Optimizing for non-old Hangul users; no
	more waste of decompose and compose.
	(render_syllable): The string argument is now in UTF-8.	Normalization
	is now done only when the entire sequence is equivalent to a
	precomposed syllable.
	(render_isolated_tone): Conditioned out tone mark's dummy base
	character drawing.

2006-12-17  Behdad Esfahbod  <[e-mail]>

	* pango/pangocairo-render.c (pango_cairo_renderer_draw_glyphs):

	Patch from James Su

	* pango/pangofc-fontmap.c (pango_fc_face_describe), (create_face),
	(pango_fc_family_list_faces): Create fake Bold, Italic, and Bold
	Italic faces for fonts that do not have one.

2006-12-13  Gwenole Beauchesne  <[e-mail]>

	Bug 385478 – Fix tests on OPD platform

	* pango/check.defs: Improve symbols extraction for OPD-based
	platforms (e.g. ppc64, ia64).

2006-12-13  Behdad Esfahbod  <[e-mail]>

	Bug 385321 – Worst case expansion for Sinhala
	Patch from Harshula

	* modules/indic/indic-ot-class-tables.c: Change worst case expansion
	for Sinhala from 3 to 4.  This is only superficial because Pango
	doesn't appear to ever use the worst case expansion value.

2006-12-08  Behdad Esfahbod  <[e-mail]>

	Red Hat Bug 211574: [hi/ml/si_LK] cursor naviation is wrong when
	using ZWJ (200d)
	Patch from LingNing Zhang

	* modules/indic/indic-lang.c (indic_engine_break): Handle cursor

	Composed char is not rendering properly
	Patch from LingNing Zhang

	* modules/indic/indic-ot.c (indic_ot_reorder): Fix it!

2006-12-07  Behdad Esfahbod  <[e-mail]>

	* pango/pango-layout-private.h:
	* pango/pango-layout.c (pango_layout_get_extents_internal),
	(pango_layout_get_extents), (pango_layout_clear_lines),
	(pango_layout_line_leaked), (pango_layout_line_get_extents),
	(pango_layout_iter_copy), (pango_layout_get_iter),
	(pango_layout_iter_get_layout_extents):
	Cache layout ink and logical extents.

2006-12-06  Behdad Esfahbod  <[e-mail]>

	* configure.in:
	* pango/Makefile.am:
	New generated public header file pango-features.h.  Currently contains
	the version information.  In the future, can be expanded to define
	which backends have been enabled, etc.

	* pango/pango.def:
	* pango/pango-utils.h:
	* pango/pango-utils.c:
	New public macros and functions: PANGO_VERSION_ENCODE(),
	PANGO_VERSION_MAJOR, PANGO_VERSION_MINOR, PANGO_VERSION_MICRO,
	PANGO_VERSION, PANGO_VERSION_STRING, PANGO_VERSION_CHECK(),
	pango_version(), pango_version_string(), pango_version_check().

	* docs/pango-docs.sgml:
	* docs/pango-sections.txt:
	* docs/tmpl/pango-version.sgml:
	Docs for new symbols, in a new section.

	* examples/renderdemo.c (show_version):
	If run-time Pango lib version is different than the compile-time one,
	show that one too.

	* pango/pango.h:
	#include <pango-utils.h> as well as almost all other public pango-*.h
	headers (though, the other ones were already included indirectly).
	The only public pango-*.h header pango.h shouldn't include are
	pango-ot.h (which is really misnamed) and pango-modules.h (that should
	not be needed by 99.99% users anyway).

	* docs/Makefile.am:
	* docs/check.docs: Test to check that all symbols are documented and
	properly hooked into documentation tree.

	* pango/pango.rc.in:
	* pango/pangoft2.rc.in:
	* pango/pangowin32.rc.in:
	Update, reflecting some internal symbol changes.

	* pango/check.defs: Improve.

2006-12-06  Behdad Esfahbod  <[e-mail]>

	* examples/renderdemo.c (do_output): Set context language to
	pango_language_get_default() instead of hardcoding "en-US".

	* pango/pango-utils.c (pango_language_get_default): Improve docs.

2006-12-06  Behdad Esfahbod  <[e-mail]>

	Bug 333982 – Fallback to $LANG whenever NULL PangoLanguage is used
	Patch from LingNing Zhang

	* docs/pango-sections.txt:
	* docs/tmpl/utils.sgml:
	* pango/pango-context.c:
	* pango/pango-types.h:
	* pango/pango-utils.c (_pango_get_lc_ctype),
	(pango_language_get_default):
	* pango/pango.def:
	New public function pango_language_get_default().  Note that, this
	does not make Pango fallback to the default language automatically,
	but the user can use this function to set the default language of the
	locale on a context:

	  pango_context_set_language (context, pango_language_get_default());

	Bug 373856 – Wish: Function to convert a GdkColor to a string
	Patch from Matthew Barnes

	* docs/pango-sections.txt:
	* docs/tmpl/text-attributes.sgml:
	* pango/pango-attributes.h:
	* pango/pango.def:
	* pango/pango-color.c (pango_color_to_string):
	New public function pango_color_to_string().

	Red Hat Bug 216850: Issue in combination with vowels (ml_IN)
	Patch from LingNing Zhang

	* modules/indic/indic-ot.c (indic_ot_reorder): Fix it!

	Bug 382437 – tests/testboundaries fails

	* configure.in: Require libthai >= 0.1.7

2006-12-06  Behdad Esfahbod  <[e-mail]>

	* examples/Makefile.am:
	* examples/test-gurmukhi.txt:
	Gurmukhi test text from supreet sethi.

2006-12-05  Behdad Esfahbod  <[e-mail]>

	* docs/pango-sections.txt:
	* docs/tmpl/layout.sgml:
	* pango/pango-layout.c (pango_layout_get_lines_readonly),
	(pango_layout_get_line_readonly),
	(pango_layout_iter_get_run_readonly),
	(_pango_layout_iter_get_line), (pango_layout_iter_get_line),
	(pango_layout_iter_get_line_readonly):
	* pango/pango-layout.h:
	* pango/pango-renderer.c (pango_renderer_draw_layout):
	* pango/pango.def:
	Add new functions:
		pango_layout_get_line_readonly()
		pango_layout_get_lines_readonly()
		pango_layout_iter_get_line_readonly()
		pango_layout_iter_get_run_readonly()
	These should be used when you do not intend to modify the run/line,
	which is more than most of the time.  So, update your app, benefit
	from more optimizations (in this case, line extents caching)!

	* === Released 1.15.1 ===

	* configure.in: Version 1.15.1

	* NEWS: Updated.

2006-12-04  Behdad Esfahbod  <[e-mail]>

	Bug 135683 – Cache glyphstring extents

	Cache line extents.  This avoids the final pango_font_get_glyph_extents()
	call per glyph per layout rendering.  Now we don't make any
	pango_font_get_glyph_extents() calls when rendering a layout (some
	conditions apply).

	* pango/pango-layout.c (pango_layout_get_lines),
	(pango_layout_get_line), (pango_layout_line_leaked),
	(pango_layout_line_get_extents), (pango_layout_line_new),
	(pango_layout_iter_get_run), (pango_layout_iter_get_line): 
	Cache line extents.  Line extents are cached only if the user doesn't
	have a pointer to the line or any of its runs.  Functions that give
	away such pointers mark the line as "leak"ed.

	* pango/pango-layout.c (pango_layout_index_to_line_and_extents),
	(pango_layout_xy_to_index), (pango_layout_index_to_pos):
	Use _pango_layout_iter_get_line() which is like
	pango_layout_iter_get_line() but doesn't leak the line.

	* pango/pango-layout-private.h: Add pango_layout_iter_get_line()
	duplicate _pango_layout_iter_get_line_readonly() that doesn't leak
	the line.

	* pango/pango-renderer.c (pango_renderer_draw_layout): Use
	_pango_layout_iter_get_line_readonly().

2006-12-04  Behdad Esfahbod  <[e-mail]>

	* pango/pangocairo-render.c (_pango_cairo_renderer_draw_frame):
	Improve upon last change.  Suggested by Carl Worth: use
	cairo_rectangle(x + width, y, -width, height) to do a rectangle with
	the other orientation.

2006-12-04  Behdad Esfahbod  <[e-mail]>

	* pango/pangocairo-render.c (_pango_cairo_renderer_draw_frame),
	(_pango_cairo_renderer_draw_box_glyph),
	(_pango_cairo_renderer_draw_unknown_glyph):
	Fix handling of boxes drawn in do_path mode.  Previously we were
	doing one rectangle and stroke it if in show mode, and leave it alone
	if in path mode.  That doesn't really work.  Now we do two rectangles,
	for the outer and inner rects of the box border, but with different
	orientations, such that pango_cairo_layout_path(); cairo_fill(); works
	for hexboxes now.

	Red Hat Bug 211964: [ta] Rendering issue with Tamil
	Patch from LingNing Zhang

	* modules/indic/indic-ot-class-tables.c (indic_ot_find_syllable):
	Handle 2 split matra.

	(pango_renderer_draw_trapezoid), (pango_renderer_draw_glyph),
