changelog.pre-1-16

Pango is a library for layout and rendering of text, with an emphasis on internationalization. Pang

	(pango_renderer_set_color), (pango_renderer_get_color),
	(pango_renderer_part_changed), (pango_renderer_prepare_run),
	(pango_renderer_set_matrix): Replace PANGO_IS_RENDERER with
	PANGO_IS_RENDERER_FAST that is just a NULL-check.

2006-12-01  Behdad Esfahbod  <[e-mail]>

	Red Hat Bug 213632: ZWJ (200d) and ZWNJ (200c) showing same output
	Patch from LingNing Zhang

	* modules/indic/indic-ot.c (indic_ot_reorder): Handle ZWNJ.

2006-12-01  Behdad Esfahbod  <[e-mail]>

	* pango/pango-layout.c (pango_layout_run_get_width), (update_run),
	(pango_layout_iter_copy), (pango_layout_iter_get_run_extents):
	Don't cache run_logical_rect in PangoLayoutIter.  Just cache run_width
	that can be fastly computed using pango_glyph_string_get_width().
	Avoids one pango_font_get_glyph_extents() call per glyph per layout
	rendering.  We are down to 1 now.

2006-11-30  Behdad Esfahbod  <[e-mail]>

	* pango/pango-layout.c (pango_layout_get_extents_internal):  Rework
	the way we compute the real_width to avoid calling
	pango_layout_get_extents(), and so, avoid one
	pango_font_get_glyph_extents() call per glyph per layout rendering.
	We now make 2 such calls.

2006-11-30  Behdad Esfahbod  <[e-mail]>

	* pango/pango-renderer.c (pango_renderer_draw_layout_line):
	Don't call into pango_glyph_string_extents() if we don't need anything
	out of it!  (Ok, that function returns immediately in that case, but
	still, avoiding the call overhead.)

2006-11-30  Behdad Esfahbod  <[e-mail]>

	* pango/pangocairo-render.c (acquire_renderer), (release_renderer):
	Use G_LOCK_* wrappers for GStaticMutex.

2006-11-28  Behdad Esfahbod  <[e-mail]>

	* pango/pangocairo-font.c (_pango_cairo_font_install),
	(_pango_cairo_font_get_font_face),
	(_pango_cairo_font_get_scaled_font):
	* pango/pangocairo-private.h:
	* pango/pangocairo-render.c (pango_cairo_renderer_draw_glyphs):
	Revert two of the cast changes from last commit, to make sure the
	test-pangocairo-fontmap-mismatch test doesn't crash.

2006-11-28  Behdad Esfahbod  <[e-mail]>

	* pango/pangocairo-fcfont.c (pango_cairo_fc_font_get_font_face),
	(pango_cairo_fc_font_install), (pango_cairo_fc_font_finalize),
	(pango_cairo_fc_font_get_metrics), (pango_cairo_fc_font_shutdown),
	(_pango_cairo_fc_font_new):
	* pango/pangocairo-fcfontmap.c
	(pango_cairo_fc_font_map_set_resolution),
	(pango_cairo_fc_font_map_get_resolution_cairo),
	(pango_cairo_fc_font_map_get_renderer),
	(pango_cairo_fc_font_map_finalize),
	(pango_cairo_fc_font_map_get_resolution_fc),
	(pango_cairo_fc_font_map_create_font):
	* pango/pangocairo-font.c (_pango_cairo_font_install),
	(_pango_cairo_font_get_font_face),
	(_pango_cairo_font_get_scaled_font),
	(_pango_cairo_font_get_hex_box_info):
	* pango/pangocairo-fontmap.c (pango_cairo_create_layout):
	* pango/pangocairo-render.c (set_color),
	(_pango_cairo_renderer_draw_unknown_glyph),
	(pango_cairo_renderer_draw_glyphs),
	(pango_cairo_renderer_draw_rectangle),
	(pango_cairo_renderer_draw_error_underline):
	Use simple, fast, casts instead of PANGO_CAIRO_*() macros where the
	object cannot have reached us if it wasn't of the right type.

	Bug 371388 – Add Thai langauage engine
	Patch from Theppitak Karoonboonyanan

	* configure.in: Look for libthai and enable thai-lang module.
	* modules/thai/Makefile.am: Hook thai-lang module.

	* modules/thai/thai-lang.c: New Thai language engine that uses libthai

	(_pango_cairo_do_glyph_string), (_pango_cairo_do_layout_line),
	(_pango_cairo_do_layout):  Make renderer-cache really thread-safe this
	time.  Last try was not quite thread-safe theoretically, because
	pointer assignments are not necessarily atomic on some archs.  Anyway,
	this one should do it.

	* pango/pangocairo-render.c (acquire_renderer), (release_renderer),
	(_pango_cairo_do_glyph_string), (_pango_cairo_do_layout_line),
	(_pango_cairo_do_layout): Instead of using a per-fontmap renderer, use
	a locally cached one, but make sure only one thread uses the cached
	renderer.  Fixes the raciest point in pangocairo.
