As discussed with ifreund on irc. This avoids extra allocation in case
of all_outputs and confusion in case of active_outputs (because with the
Output embedded in the Node, i thought its value was copied instead of
its pointer).
- Remove advertise_view and advertise_done events. Using the information
provided by these for any purpose would make the layout far less
predictable. Futhermore, in the months this has been available for use,
to my knowledge nobody has actually used it for anything useful.
- Replace the set/mod layout value events with a single user_command
event. This simplifies the protocol and is more flexible for clients.
- Add a layout_name argument to the commit request. This name is an
arbitrary, user-facing string that might, for example, be displayed by a
status bar. This was present in early drafts of the protocol, but was
removed in favor of river-options. Since river-options itself has since
been removed and this feature is nice to have, re-add it.
- Rename main factor to main ratio in rivertile. The "factor" name was
just legacy from dwm, "ratio" is much more accurate.
The Layout struct holds a pointer to the Output which becomes invalid
when the Output is destroyed so we must ensure all the layouts of an
Output are destroyed first.
Options are now all global but may be overridden per-output. If an
output local value is requested but none has been set, the global value
is provided instead. This makes for much better ergonomics when
configuring layout related options in particular.
Replace the current layout mechanism based on passing args to a child
process and parsing it's stdout with a new wayland protocol. This much
more robust and allows for more featureful layout generators.
