Oran Agra 59b4af8d59 Position Independent Code (PIC) support in autofit module.
* include/freetype/internal/autohint.h add macros to init
instances of FT_AutoHinter_ServiceRec.

* src/autofit/afmodule.h declare autofit_module_class
using macros from ftmodapi.h,
when FT_CONFIG_OPTION_PIC is defined create and destroy
functions will be declared.
* src/autofit/afmodule.c when FT_CONFIG_OPTION_PIC is defined
af_autofitter_service and autofit_module_class structs
will have functions to init or create and destroy them
instead of being allocated in the global scope.
And macros will be used from afpic.h in order to access them.

* src/autofit/aftypes.h add macros to init and declare
instances of AF_ScriptClassRec.

* src/autofit/afcjk.h declare af_cjk_script_class
using macros from aftypes.h,
when FT_CONFIG_OPTION_PIC is defined init function will be declared.
* src/autofit/afcjk.c when FT_CONFIG_OPTION_PIC is defined
af_cjk_script_class struct will have function to init it instead of
being allocated in the global scope.

* src/autofit/afdummy.h declare af_dummy_script_class
using macros from aftypes.h,
when FT_CONFIG_OPTION_PIC is defined init function will be declared.
* src/autofit/afdummy.c when FT_CONFIG_OPTION_PIC is defined
af_dummy_script_class struct will have function to init it instead of
being allocated in the global scope.

* src/autofit/afindic.h declare af_indic_script_class
using macros from aftypes.h,
when FT_CONFIG_OPTION_PIC is defined init function will be declared.
* src/autofit/afindic.c when FT_CONFIG_OPTION_PIC is defined
af_indic_script_class struct will have function to init it instead of
being allocated in the global scope.

* src/autofit/aflatin.h declare af_latin_script_class
using macros from aftypes.h,
when FT_CONFIG_OPTION_PIC is defined init function will be declared.
* src/autofit/aflatin.c when FT_CONFIG_OPTION_PIC is defined
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/autofit.c add new file to build: afpic.c.
* src/autofit/jamfile add new files to FT2_MULTI build: afpic.c.

Werner Lemberg 46dde4953a * src/autofit/aflatin.c (af_latin_uniranges): Expand structure to
cover all ranges which could possibly be handled by the aflatin
module (since the default fallback for unknown ranges is now the
afcjk module).  It might be necessary to fine-tune this further by
splitting off modules for Greek, Cyrillic, or other blocks.

        src/type1/t1gload.c:

          this is a major patch used to drastically improve the performance
          of loading glyphs. This both speeds up loading the glypn vector
          themselves and the auto-fitter.

          note that we've started using inline assembler with GCC to
          implement FT_MulFix, given that this function is so damn
          important for the engine's performance.

          the resulting speed-up is about 25%.
