GUD devices uses RGB565 by default for performance reasons. Allow
specifying render_bit_depth 6 to pick this format. The definition works
out if you consider the maximum number of bits per channel instead of
the average.
Arranging lock surfaces rely on the sway_output width and height being
updated, but these are only updated after the commit has been completed
and all commit listeners have executed. This means that the lock
surfaces will not be appropriately scaled to match a change in output
dimensions, and may reveal what is under the lock background.
Replace the implicit arrange through the output commit listener with an
explicit arrange after the output configuration is finalized.
This might have regressed by other transition away from output commit
listeners for other arrange tasks, but even then it would have
erroneously relied on signalling order.
Some display output hardware [1] doesn't support any of the current
formats, but works with ARGB8888. Fall back to it if available.

Instead of using a single finalized output config per output, accept a
regular list of output configs like the one ultimately stored for
configuration purposes. This allows the output management code to test
an augmented configuration while still using the same output config
logic, without having to mutate the stored configuration.
This in turn allows us to make a few APIs private. A bug note about an
existing issue with derade to off is added as well.
We always need to start out with the default configuration, regardless
of whether the config is reloading or not to ensure that config
decisions are stable given a specific configuration.
Simplify find_output_config and inline the search through the output
configs instead of using list_seq_find with a comparator function. The
new implementation will merge any amount of matched configs in order,
which will be relied upon in a future commit.
The reasoning for using a commit handler is to ensure that all paths for
output changes are correctly handled. With the centralized modeset
infrastructure in place, we can move the logic there. This allows us to
be smarter and avoid extraneous arranges, output manager updates and
transaction commits.
The side-effect is a minor duplication for the special-case
request_state, but the shared path will be relied upon further in future
commits to justify this duplication.
When doing an output configuration search, the intent is to only look
for modes if the output's configuration does not contain a specific
mode. This was done by testing if config_has_auto_mode returned false.
config_has_auto_mode had its return values backwards, leading to other
modes being tested if the output configuration had specified modes or
modelines, leading to unwanted modes being selected.
Invert the function to config_has_manual_mode to give it a clearer name,
and fix the return values in the process.
After 4e38f93f36 ("config/output: Skip VRR tests when not supported"),
the configuration search no longer touches VRR state for outputs that
are known to not support it. This also means that it will not remove VRR
if already set, which could cause output configuration to fail.
Ensure that VRR state is never set for outputs that do not support it by
adding the same test for support to queue_output_config.

Adaptive sync is a "soft" setting which we degrade of off when not
supported. Some outputs types do not support turning it off (Wayland,
X11), which makes for an awkward three-way test where we first enable,
disable and finally unset the setting.
wlr_output.adaptive_sync_supported tells us whether the output
definitely does not support making changes (backend without support,
connector without the feature), or whether it might work.
Use this to avoid wasting time on adaptive sync test that can never
succeed, and to avoid the Wayland/X11-backend specific unset step.
We were only passing the color transform when calling
wlr_scene_output_commit(). However when modesetting or pushing a
new gamma LUT we render via wlr_scene_output_build_state(). Pass
the color transform there as well.
The only reason it's included there is for a declaration of
struct sway_server, but we can just forward-declare it.
This avoids rebuilding almost all of Sway when touching server.h.
All other server.h includes are from source files, not headers.
If there's no config for the output, oc is null, but some screens might
have a default rotation, causing the log call to dereference a null
pointer.

Instead of having each search function print its various test decisions,
print the full state at the end of every search. This makes it much
clearer what state a particular test includes.
The original sway output config implementation enabled one output at a
time, testing modes, render formats and VRR support as it went along.
While this sort of fallback is easy to do, it has the downside of not
considering the effect of neighbor outputs on the configuration
viability.
With backend-wide commits, we can now better consider the effect of
neighbor outputs, but to handle the fact that we commit all outputs at
once we need to perform a more elaborate search of viable
configurations.
Implement a recursive configuration search for when the primary
configuration failed to apply.
When storing a config, we need to find the output that is being
configured to extract its identifier. output_by_name_or_id does not
return outputs that are disabled, and using this makes it impossible to
merge configurations related to disabled outputs.
Switch to all_outputs_by_name_or_id.
Fixes: https://github.com/swaywm/sway/issues/8141
If there is no output currently connected, we still want to merge
to any existing config.
It shouldn't matter to iterate over the list of outputs to do
nothing anwyays.

Fixes: 1267e47de9 ("config/output: Refactor handling of tiered configs")
Output configuration can be applied to a particular output in three
ways: As a wildcard, by connector name and by identifier. This in turn
means that three different configurations must be handled at any given
time.
In the current model, this is managed by merging new configuration into
every other matching configuration. At the same time, an additional
synthetic configuration is made which matchehes both identifier and name
at the same time, further complicating logic.
Instead, manage and store each configuration independently and merge
them in order when retrieving configuration for an output. When changes
are made to a less specific configuration, clear these fields from more
specific configurations to allow the change to take effect regardless of
precedence.
Fixes: https://github.com/swaywm/sway/issues/8048
apply_output_config_to_outputs uses the specified output config to check
which outputs to apply to, and to use as backup when no config is found.
If any config matches the output, the specified config will be
disregarded.
The only remaining user of apply_output_config_to_outputs is
reset_outputs, which called apply_output_config_to_outputs with either
the first stored wildcard config, or a new empty wildcard config.
Providing a stored or empty wildcard config is practically the same as
calling `apply_all_output_configs`. Replace uses of `reset_outputs` with
`apply_all_output_configs` and remove the now unused functions.
Introduce apply_output_configs, which applies the specified matched
output configs as a single backend commit.
Reimplement apply_output_config_to_outputs using apply_output_configs.
Applying an output config has two stages: Atomic application of
wlr_output_state, and applicaiton of non-atomic state like output
layout.
Split the latter out into finalize_output_config for use in a later
commit.
This doesn't catch the error if a background changing command is
executed via swaymsg, but improves logging.
The additional checks at least propagate if e.g. forking failed.
Previous behavior was that only if resolution and refresh rate match
exactly, the mode was accepted. As fallback, the mode with the highest
refresh rate and the same resolution was chosen.
New behavior is that the mode with the closest match for the refresh
rate is used with a limit of up to 1Hz. The fallback behavior stays the same.
Additionally, the logging was made more verbose.
