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.

Add a NULL check in `find_mapped_layer_by_client` like the one in `arrange_surface`.
7e69a7076f ("Drop wl_drm") has dropped wl_drm, however a lot of
software wasn't quite ready for this (Xwayland, libva, amdvlk).
Keep wl_drm disabled by default to pressure the wl_drm phase-out,
but add a -Dlegacy-wl-drm flag for users to restore the previous
behavior in the meantime.

It seems to be happening because of this set of events all happening
in the span of a single transaction:
1. You kill a tiled window that is the only window in a workplace.
2. Sway will destroy the workspace but not yet the container - this
makes `con->pending.workspace` NULL.
3. Cursor glyphs get recomputed causing sway to recompute if the cursor
is on a container edge.
4. That computation causes an access to the NULL workspace. Crash.
Instead of doing this roundabout thing where we get the surface from the
view, let's instead get it from the `wlr_surface_state` that we already
track in `handle_commit`. This makes the NULL state impossible which is
what the old `get_geometry` is checking for and generally cleans
things up a little bit.
Also don't check if the geometry x/y changed, those will always
be 0 for xwayland.
Across a wayland compositor, there are multiple shells: It can be
a toplevel, or a layer_shell, or even something more meta like a drag
icon or highlight indicators when dragging windows around.
This object lets us store values that represent these modes of operation
and keep track of what object is being represented.
Since output layout is destroyed when the wayland display is destroyed
we run into a destroy listener order problem: Either the display starts
destroying the outputs first, in which case we're good: The existing
handling will clean up. However, things go wrong if the display decides
to destroy the output layout first. In this case, sway will hold
invalid references to the output layout as part of each output so that
when it finally goes to destroy them, sway will dereference destroyed
output layout bits.

`gcc-14` added a new warning around dangerous use of `strncpy()` withi
known overflow:
../sway/config.c: In function 'do_var_replacement':
../sway/config.c:983:33: error: '__builtin___strncpy_chk' specified bound depends on the length of the source argument [-Werror=stringop-truncation]
983 | strncpy(newptr, var->value, vvlen);
| ^
../sway/config.c:971:45: note: length computed here
971 | int vvlen = strlen(var->value);
| ^~~~~~~~~~~~~~~~~~
It's a bit fishy to rely on truncating behaviour of `strncpy()`. The
change uses `memcpy()` as more explicit way to express copy of `vvlen`
bytes.
Remove any existing executed criteria items at unmap time. If a window
gets unmapped but not destroyed, we want to reapply 'for_window'
criteria. Fixes#6905.
This reverts commit afde6369
"seat: avoid unneeded reloading xcursor theme".
Always avoiding to reload the xcursor theme prevents reloading the
cursor even when this is desired. Instead seat_configure_xcursor
can determine whether a full reload is necessary.
To stay with the spirit of the reverted change, cursors are only fully
reloaded, if the theme has changed.
Fixes#6931
3d5ae9813d added logic to change the
underlying wlr_toplevel size for floating containers, but it does it
even if the container has no actual coordinates yet. This doesn't really
make sense to update the toplevel size in this case since there's many
things that could affect the initial coordinates (sway commands,
fullscreen state, etc.). Skip this by doing a crude check to see if the
current container state has any width.
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.
When using the `map_from_region` for pen tables, we will usually make
the available area as big as possible while maintaining the proportions
with the screen.
As most of the tablets uses a 16:10 ratios while the most popular screen
ratios is still 16:9, the argument for most people should be `0x0 1x0.9`
to have the maximum effective area.
However, the argument above won't work because the current code will
treat `0x...` as a hexadecimal number, instead of setting both `x` and
`y` to `0`.
This fix allows the use of the following syntax:
```
input type:tablet_tool {
map_from_region 0x0 1x0.9
}
```
If a floating client resizes itself, sway updates several of its
internal dimensions to match but not wlr_toplevel. This means that the
next time wlroots sends a toplevel configure event, it can have wrong
coordinates that resize the client back to its old size. To fix this,
let's just use wlr_xdg_toplevel_set_size so the wlr_toplevel has the
same dimensions as sway.
Exactly the same as 0183b9d35d0ce750588e700e536b7d2e367b0d0a but the
logic is onlly applied to xdg_shell and not xwayland.
This isn't the right fix for this issue because the xwayland code also
uses this function and updating the wlr_toplevel there doesn't make
sense and also causes problems. Fixes#7722.
This reverts commit bf44690ee8.

Regular clients are not allowed to use this interface. wlroots
already sends a protocol error if a non-Xwayland client tries to
use this interface, but let's remove all temptation by hiding it
completely.
With recent wlroots changes, backends which don't support output
modes can now support being disabled.
We were always marking mode-less outputs as disabled. Stop doing
that, check whether the output takes up some space in the layout
instead.
