Tatsuyuki Ishi 0d5f1dd37c [autofit] Fix double division in stem darkening.
The old code used to divide the darkening amount by em_ratio twice,
leading to unnecessarily bold stems on certain fonts with higher
units per em (e.g. Inter). This patch fixes it.

The return value of af_loader_compute_darkening was also changed to
use 16.16 fixed point to get rid of a redundant truncation operation.
This should slightly improve the precision, although it's still
bottlenecked by the emboldening function, which uses 26.6 fixed point.

* src/autofit/afloader.[ch]
(af_loader_compute_darkening): Return FT_Fixed.
(af_loader_embolden_glyph_in_slot): Revise calculations.

Werner Lemberg 9ac9060df0 [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

Werner Lemberg 37412ff9f4 Don't use macro names that contain `__' [1/2].
Such macro names are reserved for both C and C++.

*/*: Replace macros of the form `__XXX_H__' with `XXX_H_'.

Nikolaus Waxweiler bf2ba9e3d4 [autofit] Implement darkening computation function.
This is a crude adaption of the original `cf2_computeDarkening'
function.

* src/autofit/afloader.c (af_intToFixed, af_fixedToInt,
af_floatToFixed): New macros, taken from `cf2fixed.h'.
(af_loader_compute_darkening): New function.
* src/autofit/afloader.h: Updated.

Behdad Esfahbod c27336567b [autofit] Allocate hints object on the stack.
This avoids one malloc per load.

* src/autofit/afloader.h (AF_LoaderRec): Change type of `hints' to
`AF_GlyphHints'.
Update prototype.

* src/autofit/afloader.c (af_loader_init): Use `AF_GlyphHints'
parameter instead of `FT_Memory'.
(af_loader_done): Directly reset `load_hints'.
(af_loader_load_g): Updated.

* src/autofit/afmodule.c (af_autofitter_load_glyph): Use local
`hints' object.

Behdad Esfahbod a4117fbda7 [autofit] Reuse slot glyph loader.
No need to create a new glyph loader; we can reuse the one from
`slot->internal->loader'.  It's hard to tell why it was written that
way originally, but new code looks sound and correct to me, and
avoids lots of allocations.

* src/autofit/afloader.c (af_loader_init): Change return type to
`void'.
Don't call `FT_GlyphLoader_New'.
(af_loader_reset): Don't call `FT_GlyphLoader_Rewind'.
(af_loader_load_g): Update code to use `internal->loader', which
doesn't need copying of data.

* src/autofit/afloader.h (AF_LoaderRec): Remove `gloader' member.
Update prototype.

* src/autofit/afmodule.c (af_autofitter_load_glyph): Updated.

Behdad Esfahbod 89bc8d4de7 [autofit] Allocate AF_Loader on the stack instead of AF_Module.
Stop sharing a global `AF_Loader'.  Allocate one on the stack during
glyph load.

Right now this results in about 25% slowdown, to be fixed in a
following commit.

With this patch loading glyphs from different faces from different
threads doesn't immediately crash in the autohinting loader code.

Bugs:

  https://bugzilla.redhat.com/show_bug.cgi?id=1164941

* src/autofit/afloader.c (af_loader_init): Pass

argument.

Move typedef for `AF_Module' to...

* src/autofit/afmodule.h: ... this place.
No longer include `afloader.h'.

David Turner f546bacdcf * src/sfnt/Jamfile: removing "ttcmap" from the list of sources
* src/cache/*, include/freetype/cache/*: fixing a bug after heavy
        testing. The current sources are now "release candidates" for the
        final version of the cache sub-system

        * Jamfile: updating "refdoc" target, and adding "autohint" to the
        list of modules to build. Both the autohinter and autofitter will be
        built by default. But which one will be used is determined by
        the content of "ftmodule.h"

        * src/autofit/*: much updates, but the code is still buggy as hell.
        Aargh..
