* Version 2.10.0 released.
Tag sources with `VER-2-10-0'.
* docs/VERSION.TXT: Add entry for version 2.10.0.
* docs/CHANGES: Updated.
* README, Jamfile (RefDoc), src/base/ftver.rc,
builds/wince/vc2008-ce/index.html: s/2.9.1/2.10.0/, s/291/2100/.
* include/freetype/freetype.h (FREETYPE_MINOR): Set to 10.
* builds/unix/configure.raw (version_info): Set to 23:0:17.
* CMakeLists.txt (VERSION_MINOR): Set to 10.
(VERSION_PATCH): Set to 0.
* builds/ (version, winversion): Since the minor version
number has two digits now, never omit the patch number. We would
get ambiguous zip file names otherwise.
(dist): Remove remnants of `docmaker' tool.
(do-dist): Remove unused intermediate files.

[psaux] Fix use of uninitialized memory (#55832).
* src/psaux/psintrp.c (cf2_interpT2CharString): The call to
`cf2_arrstack_setCount' may fail because the allocator ran out of
memory. When this happens the stack is still written to before the
error condition is checked. This means that FreeType writes outside
of allocated memory. This commit moves the error check prior to the
stack assignment, hence the function now properly returns with an
error condition.

* src/base/ftbitmap.c (FT_Bitmap_Blend): No fractional offsets.
The function only provided a framework without an actual
implementation, which this commit removes.

[truetype] Apply MVAR hasc, hdsc and hlgp metrics to current FT_Face metrics.
Instead of setting typo or win metrics as the new `FT_Face' metrics
indiscriminately, apply only typo deltas to the currently active
`FT_Face' metrics. This prevents line height differences when the
default outlines were used as the regular face and instances for
everything else, for example.

the `FT_Face's ascender, descender, and height. Otherwise, fall
back to old behavior.

[psaux] Fix closepath (#55414).
All of the Type 1 path building is done with code common to the
revised CFF engine, with the exception of closepath, which was still
calling ps_builder_close_contour(), thus previously cached segments
were not always written to the path, and glyph corruption, or even
invalid outlines were possible.

Fix handling of `FT_Bool'.
Before this commit we had code like
(FT_Bool)( globals->glyph_styles[gindex] & 0x8000)
Since `FT_Bool' is defined to be an `unsigned char', the code
evaluated to something like
(unsigned char)( 0x8532 & 0x8000)
which in turn expanded to
(unsigned char)( 0x8000)
and finally yielded 0x00 – i.e., false – not as expected.
Problem reported and analyzed by Tony Smith <>.
* include/freetype/fttypes.h (FT_BOOL): Add a comparison against
zero so that we always have a Boolean expression.

Improve auto-hinter handling of bitmap fonts (#54681).
For bitmap fonts, `FT_Load_Glyph' should either return an error or
not set the format to `FT_GLYPH_FORMAT_OUTLINE'. However, in this
case `FT_Load_Glyph' calls into the auto-hinter which calls back
into `FT_Load_Glyph' with `FT_LOAD_NO_SCALE' in the flags, which
marks the glyph as `FT_GLYPH_FORMAT_OUTLINE' with an empty path
(even though it doesn't have any path). It appears that the
auto-hinter should not be called when the face doesn't have
outlines. The current test for using the auto-hinter in
`FT_Load_Glyph' checks whether the driver supports scalable
outlines, but not if the face supports scalable outlines.
* src/base/ftobjs.c (FT_Load_Glyph): Directly check whether we have
scalable outlines.

[pcf] Replace charmap implementation.

Triggered by

`opened_frame' to trace whether a frame must be closed at the end of

close the frame after loading the header, then use another frame for
the remaining part of the glyph later on.

[sfnt] Preliminary support of coloured layer outlines (#44689).
This commit enables OpenType's COLR/CPAL table handling; a typical
application are color emojis that can be scaled to any size.
If the color palette does not exist or is invalid, the rendering
step rasterizes the outline instead. The current implementation
assumes that the foreground is black.

Fix DLL compilation on Solaris.
AC_COMPILE_IFELSE only tries to compile a `*.c' to a `*.o'. The
Solaris Studio 12.1 through 12.5 compilers see the
`-fvisibility=hidden' flag, but ignore it with a warning of:
cc: Warning: Option -fvisibility=hidden passed to ld,
if ld is invoked, ignored otherwise
AC_LINK_IFELSE does the compile and then tries to link the result,
at which point the Solaris linker will issue an error:
ld: fatal: option '-fvisibility=hidden' is incompatible with
building a dynamic executable
If we don't use AC_LINK_IFELSE to catch the error, then configure
will fail further tests which attempt to link, such as those testing
dependencies like `libbz2'.
Also, don't try adding `-fvisibility' if we have already added
`-xldscope', just use one of them, since Sun Studio 12 and earlier
compilers only issue a warning, and don't try passing through to the
linker to generate an error, so AC_LINK_IFELSE doesn't catch them.
Tested on Solaris 11.4 beta with compiler versions:
Sun Studio 8 (Sun C 5.5)
Sun Studio 10 (Sun C 5.7)
Sun Studio 11 (Sun C 5.8)
Sun Studio 12 (Sun C 5.9)

* CMakeLists.txt, builds/cmake/FindHarfBuzz.cmake: Extensive
modernization measures.
This brings up the minimum required CMake version to 2.8.12.
The installation paths follow the GNU defaults now, e.g. installing on a
64 bit host will place binaries into the lib64/ folder on e.g. Fedora.
Symbols are hidden by default (e.g. `-fvisibility=hidden' on GCC).
CMake will no longer look for a C++ compiler.
Library and .so version now match the Autotools build.
Comments in the build file and informational messages now use platform
agnostic example commands.
ftoption.h and ftconfig.h are written directly without a redundant `-new'
External dependencies are expressed as option()s and will turn up as such
in cmake-gui.
Internal: Properties such as dependencies and include directories are now
privately set on the freetype library instead of globally.
The CPack definitions have been cleaned up, the `make dist' has been
removed. Source packages generated with CPack don't contain Autotools
files and aren't used by the maintainers anyway.
On Windows, src/base/ftver.rc is compiled to decorate the library with
version and copyright information.
A pkg-config file is now generated and installed.

[type1] Allow (again) `/Encoding' with >256 elements (#52464).
In version 2.6.1, this has been disallowed to better reject
malformed fonts; however, this restriction was too strong. This
time, we only take the first 256 elements into account, since
encoding arrays are always accessed with a 8bit integer, according
to the PostScript Language Reference.

Simplify code of test that checks cpp's computation of bit length
(the test previously created an empty `ftoption.h' file and deleted

create `ftoption.h' (no idea why this happens).

[psaux] Fix CFF advance widths. (#52466)
Glyph advance widths were being written to the new `PS_Decoder' but not
saved to the underlying format specific decoder. This caused pure CFF

field to pointer.

Use Adobe hinting engine for `light' hinting of both CFF and Type 1.
Since Ewald Hew factored the Adobe hinting engine out of the CFF
driver code, we can now use it on Type 1 (and CID) font formats, as
both have the same hinting philosophy.
This change activates the Adobe hinter when in LIGHT mode, and
therefore always unless explicitly asking for the auto-hinter. This
makes LIGHT behavior consistent with CFF fonts. As of this commit,
the hinting engine table looks as follows.
TrueType Auto v40
CFF Adobe Adobe
Type 1 Adobe Adobe

[psaux] Fix PostScript interpreter rewinding in Type 1 mode. (#52251)
The interpreter in Type 1 mode rewinds the charstring after collecting
all hints for building the initial hintmap (commit d52dd7f). However,
some charstrings use `endchar' in a final subroutine call, rewinding to
the start of that subroutine, and only a small section of the actual
glyph is drawn.
* src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_cmdENDCHAR>:
Ensure we are on the top level charstring before rewinding.

[smooth] Fix complex rendering at high ppem.
We used to split large glyphs into horizontal bands and continue
bisecting them still horizontally if that was not enough. This is
guaranteed to fail when a single scanline cannot fit into the
rendering memory pool. Now we bisect the bands vertically so that
the smallest unit is a column of the band height, which is guranteed
to fit into memory.

[smooth] Improve complex rendering at high ppem.
At large sizes almost but not exactly horizontal segments can quickly
