	(pango_ot_buffer_new), (pango_ot_buffer_destroy):
	* pango/pango-ot-private.h:
	Cache one HB_Buffer that is acquired using a lock.  A new one is
	created if the shared buffer is locked.  The shared buffer is
	cleared when released.  May want to make it free shared buffer if
	buffer->allocated is too large.  Not sure.

2007-10-11  Behdad Esfahbod  <[e-mail]>

	* pango/opentype/*: Mark internal symbols as HB_INTERNAL and
	define that to static in harfbuzz.c.

	* pango/opentype/harfbuzz-buffer-internal.h: New file.

2007-10-11  Behdad Esfahbod  <[e-mail]>

2007-10-11  Behdad Esfahbod  <[e-mail]>

	* pango/opentype/Makefile.am: Build harfbuzz.c instead of individual

	* pango/opentype/harfbuzz.c: Same here.

2007-10-11  Behdad Esfahbod  <[e-mail]>

2007-10-11  Behdad Esfahbod  <[e-mail]>

	malloc/realloc/free directly.

	* pango/pango-ot*: Update to above.

2007-10-10  Behdad Esfahbod  <[e-mail]>

	Bug 485559 – Boston Summit HarfBuzz optimizations

	* pango/opentype/*: HarfBuzz hacking to:

	  - Rename last remaining FT_Err stuff to HB_Err.

	  - Fix a couple invalid table paths to be permissive so
	    fonts work better.  Particularly GDEF table for Nafees
	    Nastaliq is loaded and works great now.

	  - Optimize harfbuzz buffer to not copy/swap for simple
	  one-to-one and "copy" GSUB operations.

	* pango/pango-ot*: Update to FT_Err to HB_Err renaming.

	end so we can use valgrind to detect leaks without noise.
