Implement the wp-tearing-control-v1 protocol allowing window to hint
the compositor that they prefer async "tearing" page flips.
Add tearing/no-tearing rules to allow the user to manually
enabled/disable tearing for a window.
Use async "tearing" page flips when a window that should be allowed to
tear is fullscreen.
This still requires several kernel patches to work with the wlroots
atomic DRM backend. For now, either set WLR_DRM_NO_ATOMIC=1 or use a
custom kernel that includes the unmerged patches (such as CachyOS).

There is not any pointer emulation for tablet tool input. This means
that only clients implementing the tablet-v2 protocol will be able to
process tablet tool input.
Tablet pad support is TODO
These are by default only enabled for debug builds but give a higher
chance of getting a usable stack trace out of bug reports as Zig's
builtin stack trace dumping code doesn't handle their absence well in
all cases yet. The cost should be negligible as river is not CPU-bound.
This is a breaking change and replaces the previous
csd-filter-add/remove and float-filter-add/remove commands.
See the riverctl(1) man page for documentation on the new system.
Now with 50% less pointer warping!
The new implementation requires the user to move the cursor into the
constraint region before the constraint is activated in order to keep
behavior more predictable.
This implementation as it stands is incomplete/buggy and will make
updating to wlr_scene more complex.
It will be reimplemented after updating to wlr_scene is complete.
It is not guaranteed that the next layout_demand event after a user_command
event has the same active tags (for example when there are no views visible).
As an example, a user could trigger a user_command while no views are visible,
then switch to a different tag set which has active views. The active tags of
the previous layout_demand may also be different.
Therefore it is impossible to correctly implement a layout generator which has
user commands apply only to the currently active tag set, which is solved by
this patch.
This makes it easier for other projects (i.e. everyone's layout
generators) to depend on the protocol xml without needing to vendor it.
The river-layout-v3 protocol should remain stable for the
forseeable future, hopefully forever. On the other hand, the current
river-control-unstable-v1 and river-status-unstable-v1 protocols
will be replaced as soon as we have time to implement better
versions. Therefore, let's not encourage usage of the protocols we
intend to remove.
This is currently unused and I don't like the approach anymore
regardless. If/when we need positional arguments (probably when
implementing the upcoming river-control protocol in rivertile)
they should be handled separately from flags.
This commit also improves the CLI error reporting to always print the
usage string if invalid arguments were passed.
- 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.
A true "default" config doesn't make sense for river. Everyone who uses
river seriously will customize their init script. Futhermore, the
current behavior of embedding the install path of the default system
config in the river binary is complex and prone to breaking.
