This commit activates the mini-HarfBuzz header files and provides the necessary infrastructure for dynamically loading HarfBuzz if `FT_CONFIG_OPTION_USE_HARFBUZZ_DYNAMIC` is defined (this macro gets set up in a follow-up commit). * src/autofit/ft-hb.c: New file, providing `ft_hb_funcs_init` and `ft_hb_funcs_done` for loading HarfBuzz dynamically. The name of the library is hold in the macro `FT_LIBHARFBUZZ`, which can be overridden. * src/autofit/ft-hb.h: Don't include `hb.h` but `ft-hb-types.h`. (hb): Modified to handle both standard linking and dynamically loading of HarfBuzz. (HB_EXTERN): New macro to load `ft-hb-decls.h`. * src/autofit/afadjust.c [FT_CONFIG_OPTION_USE_HARFBUZZ]: For the sake of dynamically loading the HarfBuzz library, replace the compile-time macro `HB_VERSION_ATLEAST` with a call to the run-time function `hb_version_atleast` where necessary – a follow-up commit will set the minimum version of HarfBuzz to 2.6.8, which provides all necessary functions needed by FreeType. * src/autofit/afmodule.h: Include `ft-hb.h`. (AF_ModuleRec) [FT_CONFIG_OPTION_USE_HARFBUZZ_DYNAMIC]: Add `hb_funcs` structure to hold pointers to the dynamically loaded HarfBuzz functions. * src/autofit/afmodule.c (af_autofitter_init, af_autofitter_done) [FT_CONFIG_OPTION_USE_HARFBUZZ_DYNAMIC]: Call `ft_hb_funcs_init` and `ft_hb_funcs_done`. * src/autofit/afshaper.h: Updated. * src/autofit/autofit.c: Include `ft-hb.c`. * src/autofit/rules.mk (AUTOF_DRV_SRC, AUTOF_DRV_H): Updated. |
