wayland-scanner output for the staging colour-management protocol, which the
native video plane uses to describe itself to the compositor as PQ / BT.2020.
Committed rather than generated at build time: the protocol only appeared in
wayland-protocols 1.41, newer than the version the distributions this app is
built for ship. Vendoring keeps the build working regardless of the host and
adds no build dependency on wayland-scanner. Generated from wayland-protocols
1.49 with wayland-scanner 1.25.0.
Nothing links these yet; the CMake wiring and the plane that uses them follow.
The local .clang-format exempts the generated sources from the runner's style.
