-Description:
-
-This version of Freetype is updated by checking out freetype from the above git
-URL, using the hash from "Revision:". Versions from 2.7.1 contain the level of
-OpenType font variations support that we require.
-
-The build files should approximate the output of
-
-make -Bn | rev | cut -d ' ' -f 1 | rev | grep "\.c$" | sort
-
-Currently the cache, patent checker (no longer used), bzip2 are excluded, as
-well as the following modules:
-t1cid_driver_class
-pfr_driver_class
-t42_driver_class
-winfnt_driver_class
-pcf_driver_class
-
-base/ftotval.c
-base/ftpfr.c
-base/ftwinfnt.c
-cid/type1cid.c
-pcf/pcf.c
-pfr/pfr.c
-type42/type42.c
-winfonts/winfnt.c
-
-Freetype depends on two header files to be supplied by the user to specify
-how to build the library, ftconfig.h and ftmodule.h (or equivalent filenames
-as defined by the FT_CONFIG_CONFIG_H and FT_CONFIG_MODULES_H #defines).
-
-The versions in include/ were generated as follows:
-
-  % cd <dir-where-you-cloned-freetype-to>
-  % bash autogen.sh
-  % ./configure
-  % cp objs/ftmodule.h ../include
-  % cp builds/unix/ftconfig.h ../include
-  % git apply patches/freetype2_symbols_visbility.patch
-
-Then we disable modules in include/ftmodule.h, then apply the symbols visibility
-patch to define the FT_EXPORT and FT_EXPORT_DEF macros to work properly when
-building a linux shared lib.
