2022-12-23 13:37:59 -07:00
Matthias Clasen 686e627bdf [paint] Set up root transform in one place
Instead of spreading this in all the tables,
make hb_paint_funcs_t provide a push/pop_root_transform
that does all the setup.

Nirbheek Chauhan 7be06f6377 meson: Override dependencies to improve usage as a subproject
With this change, harfbuzz can be consumed as a subproject without
making any changes to the build files of a project. All you need to do
is provide a wrap file with a `[provide]` section:

https://mesonbuild.com/Wrap-dependency-system-manual.html#provide-section

This is also necessary because otherwise projects need to hard-code
the subproject name, which might be `harfbuzz` when using `wrap-git` or
`harfbuzz-6.0.0` when using `wrap-file` (to build from a release
tarball). This can cause conflicts between different subprojects that
consume harfbuzz differently.

Other projects like glib, cairo, pango, etc already do this.
