The Wayland Color Management protocol has been years in the making and is needed for a client to specify the color space and HDR metadata of a surface. This color management protocol is ultimately needed for getting high dynamic range (HDR) support working out well within Wayland environments. This week an initial merge request was opened for implementing the draft color management protocol with the Weston reference compositor.
This is an important part of getting HDR working properly on Wayland, and thus making sure the Linux desktop gets full, proper HDR suport. On a related note, the Wayland Wine driver has also seen some progress, adding basic window management capabilities.
