[GSoC] src/*.*: Convert block comments to `light' style.
This monster commit was created by applying Nikhil's scripts
`docconverter.py' and `markify.py' to all C header and source files,
followed up by minor manual clean-up.
No change in functionality, of course.
I used commit f7419907bc6044b9b7057f9789866426c804ba82 from

[truetype] Add more tricky fonts.
See the report by Yang Yinsen.

[cff, truetype] Adjust behaviour of named instances.
This commit completely separates the interaction between named
instances and variation functions. In particular, resetting the
variation returns to the current named instance (if set) and not to
the base font.
As a side effect, variation functions no longer change the named
instance index.
* src/cff/cffobjs.c (cff_face_init): Use MM service's `set_instance'
function.
Also apply `MVAR' table to named instances.
* src/truetype/ttgxvar.c (TT_Get_MM_Var): Add cast.
(tt_set_mm_blend): No longer check whether requested variation
coincides with a named instance.
(TT_Set_Var_Design): Use current named instance for default
coordinates.
* src/truetype/ttobjs.c (tt_face_init): Use `TT_Set_Named_Instance'.

[sfnt, truetype] Register the tags for marginal fonts.
The first 32bit of standard TrueType variants is 0x00010000,
`OTTO', `ttcf', `true' or `typ1'. 2 marginal dfonts on legacy Mac
OS X, Keyboard.dfont and LastResort.dfont, have the sfnt resources
starting 0xA5 followed by `kbd' or `lst'. Considering the following
data could be parsed as conventional TrueType fonts, the header
checking is updated to allow these tags. It seems that recent Mac
OS X has already switched to normal TTF for these fonts.
See the discussion at
http://u88.n24.queensu.ca/exiftool/forum/index.php?topic=3931.0
* include/freetype/tttags.h (TTAG_0xA5kbd, TTAG_0xA5lst): New header
tags for Keyboard.dfont and LastResort.dfont.
* src/sfnt/sfobjs.c (sfnt_open_font): Accept the sfnt resource
starts with TTAG_0xA5kbd or TTAG_0xA5lst.
* src/truetype/ttobjs.c (tt_face_init): Accept the face with the
format tag is TTAG_0xA5kbd or TTAG_0xA5lst.

[truetype] Allocate TT_ExecContext in TT_Size instead of TT_Driver.
Previously the code had stipulation for using a per-TT_Size exec
context if `size->debug' was true. But there was no way that
`size->debug' could *ever* be true. As such, the code was always
using the singleton `TT_ExecContext' that was stored in `TT_Driver'.
This was, clearly, not threadsafe.
With this patch, loading glyphs from different faces from different
threads doesn't crash in the bytecode loader code.
* src/truetype/ttobjs.h (TT_SizeRec): Remove `debug' member.
(TT_DriverRec): Remove `context' member.
* src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Remove
`TT_ExecContext' code related to a global `TT_Driver' object.
(tt_driver_done): Don't remove `TT_ExecContext' object here but ...
(tt_size_done_bytecode): ... here.
(tt_driver_init): Don't create `TT_ExecContext' object here but ...

* src/truetype/ttinterp.c (TT_Run_Context): Remove defunct debug
code.

This is essentially a mechanical conversion, adding inclusion of
`FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for
stand-alone compiling modes of the rasterizer modules.
To convert the remaining occurrences of FT_Err_XXX and friends it is
necessary to rewrite the code. Note, however, that it doesn't harm
if some cases are not handled since FT_THROW is a no-op.

* src/truetype/ttobjs.c (tt_size_run_prep): Reset reference points.
Up to now, we simply took a snapshot of the Graphics State after the
`prep' table has been executed, and right before a glyph's bytecode
was run it got reloaded. However, as Greg Hitchcock has told us in
private communication, reference points get reset to zero in the MS
rasterizer and we follow in due course. While reasonable, this is
undocumented behaviour.
Most notably, this fixes the rendering of Arial's `x' glyph in
subpixel hinting mode.

[truetype] Scale F_dot_P down.
The dot product between freeVector and projVector or cosine of
the angle between these FT_F2Dot14 unit vectors used to be scaled up
by 4 and routinely occupied 32 bits in an FT_Long field F_dot_P.
This patch scales the value down by 2^14 instead, which simplifies
its use throughout the bytecode interpreter.
This does not lead to the loss of precision because the lower bits
are unreliable anyway. Consider two unit vectors (1,0) and (.6,.8)
for which the true value of F_dot_P is .6 * 0x40000000 = 0x26666666.
These vectors are stored as (0x4000,0) and (0x2666,0x3333) after
rounding and F_dot_P is assigned 0x26660000. The lower bits were
already lost while rounding the unit vector components.
Besides code simplification, this change can lead to better
performance when FT_MulDiv with the scaled-down F_dot_P is less
likely to use the costly 64-bit path. We are not changing the type
of F_dot_P to FT_F2Dot14 at this point.
* src/truetype/ttinterp.c (Compute_Funcs): Scale F_dot_P down by 14
bits and modify its use accordingly.
(Direct_Move, Direct_Move_Orig, Compute_Point_Displacement): Modify
the use of F_dot_P field.
* src/truetype/ttobjs.c (tt_size_run_fpgm): Change arbitrary
assignment of F_dot_P to its theoretical maximum in case we decide
to scale back its type later.

[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.

Force hinting when the font lacks its familyname.
In Type42 or Type11 font embedded in PostScript & PDF, TrueType
sfnt stream may lack `name' table because they are not required.
Hinting for nameless fonts is safer for PDFs including embedded
Chinese fonts. Written by David Bevan, see:

Generalize the concept of `tricky' fonts by introducing
FT_FACE_FLAG_TRICKY to indicate that the font format's hinting
engine is necessary for correct rendering.
At the same time, slightly modify the behaviour of tricky fonts:
FT_LOAD_NO_HINTING is now ignored. To really force raw loading
of tricky fonts (without hinting), both FT_LOAD_NO_HINTING and
FT_LOAD_NO_AUTOHINT must be used.
Finally, tricky TrueType fonts always use the bytecode interpreter
even if the patented code is used.
