* include/freetype/config/ftoption.h add FT_CONFIG_OPTION_PIC * include/freetype/internal/ftobjs.h Add pic_container member to FT_LibraryRec. Add macros to declare and init instances of FT_CMap_ClassRec. Add macros to init instances of FT_Outline_Funcs and FT_Raster_Funcs. Add macros to declare, allocate and initialize modules (FT_Module_Class). Add macros to declare, allocate and initialize renderers (FT_Renderer_Class). Add macro to init instances of FT_Glyph_Class. Add macros to declare, allocate and initialize drivers (FT_Driver_ClassRec). * include/freetype/internal/ftpic.h new file to declare the FT_PIC_Container struct and the functions to allocate and detroy it. * include/freetype/internal/ftserv.h add macros to allocate and destory arrays of FT_ServiceDescRec. * include/freetype/internal/internal.h define macro to include ftpic.h. New Files: * src/base/ftpic.c implement functions to allocate and destory the global pic_container. * src/base/basepic.h declare struct to hold PIC globals for base and macros to access them. * src/base/basepic.c implement functions to allocate, destroy and initialize PIC globals for base. * src/base/ftinit.c when FT_CONFIG_OPTION_PIC is defined implement functions that allocate and destroy ft_default_modules according to FT_CONFIG_MODULES_H in the pic_container instead of the global scope and use macro from basepic.h to access it. * src/base/ftobjs.c add calls to the functions that allocate and destroy the global pic_container when the library is created and destroyed. * src/base/jamfile add new files to FT2_MULTI build: ftpic.c and basepic.c. * src/base/ftbase.c add new files to build: ftpic.c and basepic.c. * src/base/ftglyph.c when FT_CONFIG_OPTION_PIC is defined ft_bitmap_glyph_class and ft_outline_glyph_class will be allocated in the pic_container instead of the global scope and use macros from basepic.h to access them. * src/base/ftbbox.c allocate bbox_interface stract on the stack instead of the global scope when FT_CONFIG_OPTION_PIC is defined. * src/base/ftstroke.c access ft_outline_glyph_class allocated in ftglyph.c via macros from basepic.h
