Since `make distclean` doesn't always clean up `objs/` properly, + `make dist` archives may contain some stale binaries like + `objs/.libs/libfreetype.so.6` or others. + + - `config.guess` and `config.sub` are not updated unless option + `--gnu-config-dir=DIR` is used to specify the location of these + files. + + - Some bits of the auto-generated reference documentation may + appear in slightly different order, probably due to issues related + to mkdocs and docwriter. + + As an example, the call + + scripts/make_distribution_archives.py /tmp/freetype2-dist + + creates the following files under `/tmp/freetype2-dist`: + + freetype-<version>.tar.gz + freetype-<version>.tar.xz + ft<winversion>.zip + +2020-09-21 Werner Lemberg <wl@gnu.org> + + * scripts/extract_freetype_version.py: Fix regex typos. + +2020-09-21 David Turner <david@freetype.org> + + Add Meson build project file. + + Example usage: + + # Configure Meson build in directory `build-meson` to generate + # release binaries comparable to to the ones from the + # autotools/make build system. + meson setup build-meson \ + --prefix=/usr/local \ + --buildtype=debugoptimized \ + --strip \ + -Db_ndebug=true + + # After configuring the Meson build with the above command, + # compile and install to `/usr/local/`; this includes a pkg-config + # file. + ninja -C build-meson install + + # Alternatively, compile and install to `/tmp/aa/usr/local/...` + # for packaging. + DESTDIR=/tmp/aa ninja -C build-meson install + + # Generate documentation under `build-meson/docs`. + ninja -C build-meson docs + + Library size comparison for stripped `libfreetype.so` generated by + all three build systems: + + -

It enables or disables + configuration macro variables based on the available dependencies. + This is similar to what other build systems are using (i.e., Meson's + `configure_file()` command is not used here). + + * scripts/extract_freetype_version.py: New script invoked by + `meson.build` to extract the FreeType version number from + `<freetype/freetype.h>`. + + * scripts/extract_libtool_version.py: New script invoked by + `meson.build` to extract the libtool `revision_info` data from + `builds/unix/configure.raw`, and to generate the corresponding + shared library suffix. + + * scripts/generate_reference_docs.py: New script invoked by + `meson.build` to generate the FreeType 2 reference documentation + (using the `docwriter` and `mkdocs` packages, which must be already + installed). + +2020-09-11 Alexei Podtelezhnikov <apodtele@gmail.com> + + [raster] Improve the second pass (#58373). + + Besides dropout control the second horizontal sweep is supposed to + clean up straight horizontal edges that are mishandled by the first + vertical sweep when a line passes through pixel centers.
