+
+    [GPOS] Fix interaction of mark attachments and cursive chaining
+
+    Fixes https://github.com/behdad/harfbuzz/issues/211
+
+    What happens in that bug is that a mark is attached to base first,
+    then a second mark is cursive-chained to the first mark.  This only
+    "works" because it's in the Indic shaper where mark advances are
+    not zeroed.
+
+    Before, we didn't allow cursive to run on marks at all.  Fix that.
+    We also where updating mark major offsets at the end of GPOS, such
+    that changes in advance of base will not change the mark attachment
+    position.  That was superior to the alternative (which is what
+    Uniscribe
+    does BTW), but made it hard to apply cursive to the mark after it
+    was positioned.  We could track major-direction offset changes and
+    apply that to cursive in the post process, but that's a much trickier
+    thing to do than the fix here, which is to immediately apply the
+    major-direction advance-width offsets...  Ie.:
+
+    https://github.com/behdad/harfbuzz/issues/211#issuecomment-183194739
+
+    If this breaks any fonts, the font should be fixed to do mark
+    attachment
+    after all the advances are set up first (kerning, etc).
+
+    Finally, this, still doesn't make us match Uniscribe, for I explained
+    in that bug.  Looks like Uniscribe applies minor-direction cursive
+    adjustment immediate as well.  We don't, and we like it our way, at
+    least for now.  Eg. the sequence in the test case does this:
+
+    - The first subscript attaches with mark-to-base, moving in x only,
+    - The second subscript attaches with cursive attachment to first
+    subscript
+      moving in x only,
+    - A final context rule moves the first subscript up by 104 units.
+
+    The way we do, the final shift-up, also shifts up the second subscript
+    mark because it's cursively-attached.  Uniscribe doesn't.  We get:
+
+    [ttaorya=0+1307|casubscriptorya=0@-242,104+-231|casubscriptnarroworya=0@20,104+507]
+
+    while Uniscribe gets:
+
+    [ttaorya=0+1307|casubscriptorya=0@-242,104+-211|casubscriptnarroworya=0+487]
+
+    note the different y-offset of the last glyph.  In our view,
+    after cursive,
+    things move together, period.

+
+    MSVC builds: Add support to build DirectWrite shaping backend
+
+    Add into the NMake Makefiles to build the DirectWrite shaping backend,
+    but as PR #134 mentions, this is considered to be in an experimental
+    state,
+    so don't include this in the build by default for now.  This is
+    most probably
+    going to replace the Uniscribe backend eventually, since DirectWrite
+    is meant
+    to be Uniscribe's replacement, and is needed for Windows Store apps
+    if a
+    system shaping API is to be used.

+Author: Chun-wei Fan <fanchunwei@src.gnome.org>
+Date:   Tue Nov 3 19:00:42 2015 +0800
+
+    build: Support Visual Studio builds using NMake
+
+    This adds a set of NMake Makefiles that can be used to build
+    HarfBuzz, from
+    the standard basic build building the minimal HarfBuzz DLL (consisting
+    of OpenType, fallback and Uniscribe support only), to a full
+    fledged build
+    consisting of GLib and FreeType support, as well as building the
+    utilities,
+    the test programs in src/ and test/api, and HarfBuzz-ICU and
+    HarfBuzz-GObject, and up to building the introspection files.
+    This means a
+    flexible build mechanism is supported here, so anything that is
+    supported
+    for a Windows build (code-wise), should all be supported by this build
+    system.
+
+    As in an earlier commit, the source listings are shared with the
+    autotools
+    builds with the various Makefile.sources in src/, src/hb-ucdn and
+    util/, and
+    this set of NMake Makefiles will transform these lists into the
+    form they
+    want.
+
+    In the current form, all the test programs in test/api pass, and
+    this has
+    been checked successfully with 'make -j8 distcheck'.

+
+    MSVC builds: Add a pre-configured config.h(.win32) template
+
+    This adds a pre-configured config.h template that can be used
+    for Visual
+    Studio builds, where autotools is not normally available.  This has
+    the
+    configs that are suitable for Visual Studio builds, as well as all the
+    features used for Windows builds enabled (HAVE_OT, HAVE_FALLBACK and
+    HAVE_UNISCRIBE).
+
+    Note that the optional features are not enabled here, they are
+    enabled by
+    /D's (or -D's) in the NMake Makefiles as requested.

+
+    [OT] Get list of lookup subtables once and loop through them
+
+    This speeds up shaping the Amiri font by over 15%.
+
+    This was primarily needed for my work on OpenType GX, since
+    we will be collecting only sublookups that are "active" for
+    current font instance; but it's a nice boost in general as
+    well.
+
+    We might, in the future, collect subtables in the lookup_accel.
+    That would also allow us to do a per-subtbale set-digest, which
+    should speed things up some more, specially for ContextChainFormat3
+    lookups...  Amiri, for example, contains one lookup with 53
+    subtables!

+Overview of changes leading to 1.2.0
+Friday, February 19, 2016
+====================================
+
+- Fix various issues (hangs mostly) in case of memory allocation failure.
+- Change mark zeroing types of most shapers from BY_UNICODE_LATE to
+  BY_GDEF_LATE.  This seems to be what Uniscribe does.
+- Change mark zeroing of USE shaper from NONE to BY_GDEF_EARLY.  That's
+  what Windows does.
+- Allow GPOS cursive connection on marks, and fix the interaction with
+  mark attachment.  This work resulted in some changes to how mark
+  attachments work.  See:
+  https://github.com/behdad/harfbuzz/issues/211
+  https://github.com/behdad/harfbuzz/commit/86c68c7a2c971efe8e35b1f1bd99401dc8b688d2
+- Graphite2 shaper: improved negative advance handling (eg. Nastaliq).
+- Add nmake-based build system for Windows.
+- Minor speedup.
+- Misc. improvements.
