WIP: unstable: add color management protocol
This protocol specifies a way for a client to set the color space and HDR metadata of a surface and to get information about the color spaces and HDR capabilities of outputs.
Signed-off-by: Sebastian Wick email@example.com
WIP because there are a few open questions and no HDR support yet.
This version was previously sent to wayland-devel https://lists.freedesktop.org/archives/wayland-devel/2019-November/040978.html
@vitalyp has continued on top of Sebastian's branch:
We are developing this proposal by filing sub-MRs in Sebastian's fork and merging them into the branch this MR is based on.
Eventually everything in this MR will be squashed into a single patch before landing.
