This makes it so callers no longer need to juggle with raw pixel
pointers anymore, and only need a single wlr_buffer-based codepath.
Additionally, cursors can be unloaded without risking use-after-free.
The mailing list has never been used.
I think listing the deprecated functions in the release notes is
enough. I'd rather not add the burden of maintaining a separate
communication medium.
This introduces -DWLR_USE_UNSTABLE and adds information regarding the
stability status to all headers. I started with a conservative set of
headers to mark as stable:
- types/wlr_matrix.h
- util/edges.h
- util/log.h
- util/region.h
- xcursor.h
