This reverts commit c939f6aff405ca7b10b1f1538f46148bff719fcb.

That is, we work in-place even for ligatures now.

        * pango/opentype/*:
        HarfBuzz was relicensed to a more generous and simpler license.
        Adapt.  See pango/opentype/COPYING for the new license which is
        LGPL-compatible.

        Bug 488840 – harfbuzz: protect against ligid overflow

        * pango/opentype/harfbuzz-buffer.c (_hb_buffer_allocate_ligid):
        Never return zero, even in case of overflow.

        * pango/opentype/harfbuzz-impl.h: Define dummy HB_LIKELY() and
        HB_UNLIKELY(), to be filled later.

2007-10-11  Behdad Esfahbod  <behdad@gnome.org>

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

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

        * pango/opentype/harfbuzz-buffer.c: Move some code around.

2007-10-11  Behdad Esfahbod  <behdad@gnome.org>

        * pango/opentype/harfbuzz-buffer.[ch]: Rename buffer->inplace to
        buffer->separate_out with the inverted meaning, such that buffer
        is initialization is memset(0).

2007-10-11  Behdad Esfahbod  <behdad@gnome.org>

        * pango/opentype/*: Allocate buffer->positions lazily.

        Bug 485621 – Get rid of freetype memory allocator in harfbuzz

        * pango/opentype/*: Remove all occurences of FT_Memory.  Use
        malloc/realloc/free directly.

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

        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.

        Bug 302952 – The placement of a diacritic marks for an arabic ligature
        is not correct

        * pango/opentype/harfbuzz-buffer.c (hb_buffer_allocate_ligid): Don't
        use zero as allocated ligature id.  Zero means no ligature id.
