af_latin_script_class struct will have function to init it instead of
being allocated in the global scope.
Change af_latin_blue_chars to be PIC-compatible by being a two
dimentional array rather than array of pointers.
* src/autofit/aflatin2.h declare af_latin2_script_class
using macros from aftypes.h,
when FT_CONFIG_OPTION_PIC is defined init function will be declared.
* src/autofit/aflatin2.c when FT_CONFIG_OPTION_PIC is defined
af_latin2_script_class struct will have function to init it instead of
being allocated in the global scope.
Change af_latin2_blue_chars to be PIC-compatible by being a two
dimentional array rather than array of pointers.
* src/autofit/afglobal.c when FT_CONFIG_OPTION_PIC is defined
af_script_classes array initialization was moved to afpic.c and
is later refered using macros defeined in afpic.h.
New Files:
* src/autofit/afpic.h declare struct to hold PIC globals for autofit
module and macros to access them.
* src/autofit/afpic.c implement functions to allocate, destroy and
initialize PIC globals for autofit module.

* src/autofit/jamfile add new files to FT2_MULTI build: afpic.c.
extern const FT_Module_Class
(or similar for C++). However, the actual types of the variables
being declared are often different, e.g., FT_Driver_ClassRec or
FT_Renderer_Class. (Some are, indeed, FT_Module_Class.)
This works with most C compilers (since those structs begin with an
FT_Module_Class struct), but technically it's undefined behavior.
To quote the ISO/IEC 9899:TC2 final committee draft, section 6.2.7
paragraph 2:
All declarations that refer to the same object or function shall
have compatible type; otherwise, the behavior is undefined.
(And they are not compatible types.)
Most C compilers don't reject (or even detect!) code which has this
issue, but the GCC LTO development branch compiler does. (It
outputs the types of the objects while generating .o files, along
with a bunch of other information, then compares them when doing the
final link-time code generation pass.)
Patch from Savannah bug #25133.
* src/base/ftinit.c (FT_USE_MODULE): Include variable type.
* builds/amiga/include/freetype/config/ftmodule.h,
include/freetype/config/ftmodule.h, */module.mk: Updated to declare
pass correct types to FT_USE_MODULE.
* include/freetype/internal/ftcalc.h, src/base/ftcalc.c
(FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled): New
functions.
* src/cff/cffobjs.h (CFF_Internal): New struct. It is used to
provide global hinting data for both the top-font and all subfonts
(with proper scaling).
* src/cff/cffobjs.c (cff_make_private_dict): New function, using
code from `cff_size_init'.
(cff_size_init, cff_size_done, cff_size_select, cff_size_request):
Use CFF_Internal and handle subfonts.
(cff_face_init): Handle top-dict and subfont matrices correctly;
apply some heuristic in case of unlikely matrix concatenation
results. This has been discussed with people from Adobe (thanks
goes mainly to David Lemon) who confirm that the CFF specs are fuzzy
and not correct.
* src/cff/cffgload.h (cff_decoder_prepare): Add `size' argument.
* src/cff/cffgload.c (cff_builder_init): Updated.
(cff_decoder_prepare): Handle hints globals for subfonts.
Update all callers.
(cff_slot_load): Handling scaling of subfonts properly.
* src/cff/cffparse.c (cff_parse_fixed_dynamic): New function.
(cff_parse_font_matrix): Use it.
* src/cff/cfftypes.h (CFF_FontDictRec): Make `units_per_em'
FT_ULong.
* docs/CHANGES: Document it.
