[autofit] Implement Infinality's `increase glyph heights'.
This is an improved version of a similar fix contained in the
so-called `Infinality patch', taken from
http://www.infinality.net/fedora/linux/zips/freetype-infinality-2.4.10-20120616_01-x86_64.tar.bz2
which addresses various enhancements of the auto-hinter. Without
properties to control a module's metadata it wasn't possible to
adapt the patches because everything was originally controlled by
environment variables which I consider not suitable in general.
A patch to control `increase_x_height' follows.
* src/autofit/afglobal.h (AF_PROP_INCREASE_X_HEIGHT_MIN,
AF_PROP_INCREASE_X_HEIGHT_MAX): New macros.
(AF_FaceGlobalsRec): Add `increase_x_height' member.
* src/autofit/afglobal.c (af_face_globals_new): Initialize it.
* src/autofit/aflatin.c (af_latin_metrics_scale_dim),
* src/autofit/aflatin2.c (af_latin2_metrics_scale_dim): Implement
handling of `increase_x_height'.

[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,

* 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.

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

[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

* src/truetype/ttobjs.c (tt_check_trickyness_sfnt_ids): 4 sets

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.

[autofit] Return correct linear advance width values.
This was quite a subtle bug which accidentally showed up with glyph
`afii10023' of arial.ttf (version 2.76). This glyph is a composite;
the first component, `E', has an advance width of 1366 font units,
while the advance width of the composite itself (which looks like
uppercase `E' with dieresis) is 1367 font units. I think this is
actually a bug in the font itself, because there is no reason that
this glyph has not the same width as uppercase `E' without the
dieresis. Anyway, it helped identify this problem.
Using the TrueType hinter, the correct value (1367) of `afii10023'
was returned, but the autohinter mysteriously returned 1366.
Digging in the code showed that the autohinter recursively calls
FT_Load_Glyph to load the glyph, adding the FT_LOAD_NO_SCALE load
flag. However, the `linearHoriAdvance' field is still returned as a
scaled value. To avoid scaling twice, the old code in autofit reset
`linearHoriAdvance', using the `horiAdvance' field. This seemed to
work since FT_LOAD_NO_SCALE was in use, but it failed actually,
because `horiAdvance' is defined as the distance of the first
subglyph's phantom points, which in turn are initialized using the
advance width of the first subglyph. And as the given example
shows, these widths can differ.
* src/autofit/afloader.c (af_loader_load_g): Temporarily set
FT_LOAD_LINEAR_DESIGN while calling FT_Load_Glyph to get unscaled
values for the linear advance widths.
