Werner Lemberg 7e4b0fbfdd [truetype] Improve emulation of vertical metrics.
This commit also improves the start values of vertical phantom
points.  Kudos to Greg Hitchcock for help.

* src/truetype/ttgload.c (TT_Get_VMetrics): Add parameter to pass
`yMax' value.  Replace code with fixed Microsoft definition.
(tt_get_metrics): Updated.
(TT_LOADER_SET_PP): Add explanation how to initialize phantom
points, taken from both the OpenType specification and private
communication with Greg (which will eventually be added to the
standard).
Fix horizontal position of `pp3' and `pp4'.

* src/truetype/ttgload.h: Updated.

* src/truetype/ttdriver.c (tt_get_advances): Updated.

* docs/CHANGES: Updated.

Werner Lemberg ee5105107b [sfnt] Implement support for `OS/2' table version 5.
See

  http://typedrawers.com/discussion/470/new-microsoft-size-specific-design-selection-mechanism

for the announcement.

* include/freetype/tttables.h (TT_OS2): Add fields
`usLowerPointSize' and `usUpperPointSize'.  Since FreeType returns
this structure only as a pointer through `FT_Get_Sfnt_Table', there
shouldn't be any ABI problems.

* src/sfnt/ttload.c (tt_face_load_os2): Implement it.

* docs/CHANGES: Updated.

Werner Lemberg 2429dc3d7c Add CFF_CONFIG_OPTION_OLD_ENGINE configuration option.
This controls whether the old FreeType CFF engine gets compiled into
FreeType.  It is now disabled by default.

* devel/ftoption.h, include/freetype/config/ftoption.h
(CFF_CONFIG_OPTION_OLD_ENGINE): New macro.

CFF_CONFIG_OPTION_OLD_ENGINE to guard the affected code.

* docs/CHANGES: Updated.

Behdad Esfahbod 760d342d37 Add support for color embedded bitmaps (eg. color emoji).
A new load flag, FT_LOAD_COLOR, makes FreeType load color
embedded-bitmaps, following this draft specification

  https://color-emoji.googlecode.com/git/specification/v1.html

which defines two new SFNT tables, `CBDT' and `CBLC' (named and
modeled after `EBDT' and `EBLC', respectively).  The color bitmaps
are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA
pre-multiplied sRGB images.  If PNG support is available, PNG color
images as defined in the same proposed specification are supported
also.

Note that color bitmaps are converted to grayscale if client didn't
ask for color.

* builds/unix/configure.raw: Search for libpng.
Add `--without-png' option.

* devel/ftoption.h, include/freetype/config/ftoption.h
(FT_CONFIG_OPTION_USE_PNG): New macro.

* include/freetype/freetype.h (FT_LOAD_COLOR): New load flag.

* include/freetype/ftimage.h (FT_Pixel_Mode): Add

* src/sfnt/sfnt.c: Include `pngshim.c'.

* src/sfnt/ttsbit.c: Include FT_BITMAP_H and `pngshim.h'
(tt_face_load_eblc): Load `CBLC'.
(tt_sbit_decoder_init): Load `CBDT'.
(tt_sbit_decoder_alloc_bitmap): Pass load flags to select between
color and grayscale bitmaps.
Set `num_grays'.  This is used by `ftview' to choose the blending
algorithm.
(tt_sbit_decoder_load_byte_aligned,
tt_sbit_decoder_load_bit_aligned, tt_sbit_decoder_load_compound,
tt_sbit_decoder_load_image): Pass load flag.
s/write/pwrite/.
Don't call `tt_sbit_decoder_alloc_bitmap'.
Updated.
(tt_sbit_decoder_load_png) [FT_CONFIG_OPTION_USE_PNG]: New function.
(tt_sbit_decoder_load_bitmap): Pass load flag.
Handle new glyph formats 17, 18, and 19.
Call `tt_sbit_decoder_alloc_bitmap'.
Flatten color bitmaps if necessary.

Alexei Podtelezhnikov b4ac30b0ed [base] Reduce trigonometric algorithms.
After we get within 45 degrees by means of true 90-degree rotations,
we can remove initial 45-degree CORDIC iteration and start from
atan(1/2) pseudorotation, reducing expansion factor thereby.

suzuki toshiya 084abf0469 [autofit] Add bluezones for CJK Ideographs.
To remove extremas of vertical strokes of CJK Ideographs at
low resolution and make the top and bottom horizontal stems
aligned, bluezones for CJK Ideographs are calculated from
sample glyphs.  At present, vertical bluezones (bluezones
to align vertical stems) are disabled by default.  For detail, see
http://lists.gnu.org/archive/html/freetype-devel/2011-04/msg00070.html

* src/autofit/afindic.c (af_indic_metrics_init): Take AF_CJKMetric
instead of AF_LatinMetric, and initialize as af_cjk_metrics_init.
However bluezones are not initialized.
