Adds wlr_output_color_format (AUTO, RGB444, YCBCR444, YCBCR422,
YCBCR420) matching the DRM connector color format property. The DRM
backend discovers and sets this property on modeset.
The wlr-output-management-unstable-v1 protocol is extended to version 5
with a color_format enum and set_color_format request, allowing clients
to configure the output color encoding.
This sync includes minor non-breaking updates from recent years:
- Fix typos and grammatical issues (e.g. "a an" → "an", "inexistent" → "nonexistent")
- Improve description consistency with `wl_output` (e.g. name, description, make, model, serial)
- Add `destructor` annotation to relevant events (e.g. `finished` in foreign-toplevel)
- Clarify event emission timing and behavior for output management
- No functional or semantic protocol changes introduced
These changes improve the accuracy and consistency of protocol descriptions without impacting compatibility.
The following information through separate events are added:
- make
- model
- serial_number
This should allow clients to identify a display over different sessions and
load configuration data back.
A note is added that the description should be preferred when representing a
display in UI to users but as a short form for example the model could be used
in this case of course too.
