Werner Lemberg 04affa270b * src/base/ftsynth.c (FT_GlyphSlot_Oblique): Fix shear angle.
The old value was far too large (more than 20°).  The new one
corresponds to 12°, quite common in typography.

Werner Lemberg ad866e2c9a Fix `checking if gcc static flag -static works' test.
On my linux build tree, I receive yes answer in in every package I
build except freetype for this test checking if gcc static flag
`-static' works

On freetype, no is received, unless bzip2 and zlib are disabled using

  ./configure --without-bzip2 --without-zlib

The reason is that bzip2 and zlib tests add `-lz' and `-lbz2' to
LDFLAGS and this broke static flag test.

* builds/unix/configure.raw: Update CFLAGS and LDFLAGS only after
LT_INIT has run.

Infinality 79e36baebb [truetype] Support subpixel hinting.
This is the large, famous `Infinality' patch to support ClearType
bytecode which has been available from
http://www.infinality.net/blog/ for some time, and which has been
refined over the last years.  While still experimental, it is now
mature enough to be included directly into FreeType.

Most of the code is based on the ClearType whitepaper written by
Greg Hitchcock

  http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx

which gives a detailed overview of the necessary changes to the
Microsoft rasterizer so that older fonts are supported.  However, a
lot of details are still missing, and this patches provides a
framework to easily handle rendering issues down to the glyph level
of certain fonts.

Note that ClearType support is not completely implemented!  In
particular, full support for the options `compatible_widths',
`symmetrical_smoothing, and `bgr' (via the GETINFO bytecode
instruction) is missing.

* src/truetype/ttsubpix.c: New file, providing code to handle
`tweaks', this is, rules for certain glyphs in certain fonts
(including wildcards) which need a special treatment.

* src/truetype/ttsubpix.h: New file, holding the tweaking rules.

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

* include/freetype/internal/ftobjs.h (FT_PIX_FLOOR_GRID,
FT_PIX_ROUND_GRID, FT_PIX_CEIL_GRID): New macros.

* src/truetype/truetype.c [TT_USE_BYTECODE_INTERPRETER]: Include
`ttsubpix.c'.

* src/truetype/ttgload.c: Include `ttsubpix.h'.
[All changes below are guarded by TT_CONFIG_OPTION_SUBPIXEL_HINTING.]

(tt_get_metrics): Set tweak flags.
(TT_Hint_Glyph): Call `FT_Outline_EmboldenXY' if necessary.
(TT_Process_Simple_Glyph): Compensate emboldening if necessary.
(compute_glyph_metrics): Handle `compatible widths' option.
(tt_loader_init): Handle ClearType GETINFO information bits.

* src/truetype/rules.mk (TT_DRC_SRC): Updated.

* src/truetype/ttinterp.c: Include `ttsubpix.h'.
[Where necessary, changes below are guarded by
TT_CONFIG_OPTION_SUBPIXEL_HINTING.]

(Direct_Move, Direct_Move_X): Extended.
(Round_None, Round_To_Grid, Round_To_Half_Grid, Round_Down_To_Grid,
Round_Up_To_Grid, Round_To_Double_Grid, Round_Super, Round_Super_45,
SetSuperRound): Add parameter to handle the number of grid lines per
pixel.
(SET_SuperRound, ROUND_None, CUR_Func_round): Updated.
(DO_SROUND, DOS45ROUND, DO_ODD, DO_EVEN): Updated.
(DO_ROUND, DO_NROUND): Updated.

(TT_ExecContextRec): Add members for subpixel hinting support.

* src/truetype/ttobjs.h (TT_DefRecord): Add `inline_delta' member.

suzuki toshiya 6c7c3de197 [truetype] Add new versions of NEC FA family to tricky font list.
NEC FA family dated in 1996 have different checksum.
Reported by Johnson Y. Yan <yinsen_yan@foxitsoftware.com>; see

  http://lists.gnu.org/archive/html/freetype-devel/2012-06/msg00023.html

* src/truetype/ttobjs.c (tt_check_trickyness_sfnt_ids): 4 sets
of fpgm & prep table checksums for FA-Gothic, FA-Minchou,
FA-RoundedGothicM, FA-RoundedGothicB are added.  The family
names in sample PDF are truncated, thus the list of the
family names in tt_check_trickyness_family() is not updated yet.
