This does not implement the protocol, it will simply run the scanner
on the xml to generate the .c and .h files.
This is a variant of the color-management protocol that still didn't
land upstream on the wayland-protocols repository.
We are using that to experiment with the protocol, but we'll
completely drop this eventually, when the official protocol
lands.
