for a rationale.
* src/autofit/afpic.h, src/base/basepic.h, src/cff/cffpic.h,
src/pshinter/pshpic.h, src/psnames/pspic.h, src/raster/rastpic.h,
src/sfnt/sfntpic.h, src/smooth/ftspic.h, src/truetype/ttpic.h
(FT_BEGIN_HEADER, FT_END_HEADER): Move macro calls to not enclose
header files that contain FT_{BEGIN,END}_HEADER macros by
themselves.
* src/autofit/aftypes.h [FT_DEBUG_AUTOFIT]: Include
FT_CONFIG_STANDARD_LIBRARY_H earlier.
* src/truetype/ttpic.h: Include FT_INTERNL_PIC_H.
Originally FT_DEFINE_{DRIVER,MODULE,RENDERER}() macros were
designed to declare xxx_pic_{free,init} by themselves.
Because these macros are used at the end of the module
interface (e.g. ttdriver.c) and the wrapper source to build
a module as a single object (e.g. truetype.c) includes
the PIC file (e.g. ttpic.c) before the module interface,
these macros are expanded AFTER xxx_pic_{free,init} body
when the modules are built as single object.
The declaration after the implementation causes the redundant
declaration warnings, so the declarations are moved to module
PIC headers (e.g. ttpic.h). Separating to other header files
are needed for multi build.
* include/freetype/internal/ftdriver.h (FT_DEFINE_DRIVER):
Remove class_##_pic_free and class_##_pic_init declarations.
* include/freetype/internal/ftobjs.h (FT_DEFINE_RENDERER,
FT_DEFINE_MODULE): Ditto.
* src/base/basepic.h: Insert a comment and fix coding style.
* src/autofit/afpic.h: Declare autofit_module_class_pic_{free,
init}.
* src/cff/cffpic.h: Declare cff_driver_class_pic_{free,init}.
* src/pshinter/pshpic.h: Declare pshinter_module_class_pic_{free,
init}.
* src/psnames/pspic.h: Declare psnames_module_class_pic_{free,
init}.
* src/raster/rastpic.h: Declare
ft_raster{1,5}_renderer_class_pic_{free,init}
* src/sfnt/sfntpic.h: Declare sfnt_module_class_pic_{free,init}.
* src/smooth/ftspic.h: Declare
ft_smooth_{,lcd_,lcdv_}renderer_class_pic_{free,init}.
* src/truetype/ttpic.h: Declare tt_driver_class_pic_{free,init}.
* include/freetype/internal/pshints.h add macros to init
instances of PSHinter_Interface.
* src/pshinter/pshmod.h declare pshinter_module_class
using macros from ftmodapi.h,
when FT_CONFIG_OPTION_PIC is defined create and destroy
functions will be declared.
* src/pshinter/pshmod.c when FT_CONFIG_OPTION_PIC is defined
pshinter_interface and pshinter_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 pshpic.h in order to access them.
New Files:
* src/pshinter/pshpic.h declare struct to hold PIC globals for pshinter
module and macros to access them.
* src/pshinter/pshpic.c implement functions to allocate, destroy and
initialize PIC globals for pshinter module.
* src/pshinter/pshinter.c add new file to build: pshpic.c.
* src/pshinter/jamfile add new files to FT2_MULTI build: pshpic.c.
