Sway ignores SIGPIPE (by installing a SIG_IGN handler), in order to
“prevent IPC from crashing Sway”.
SIG_IGN handlers are the *only* signal handlers inherited in
sub-processes. As such, we should be a good citizen and restore the
SIGPIPE handler to its default handler.

Until now, swaybar did not have pango markup enabled by default, even if
the sway config had it on. This patch aims to mimic the i3 behavior, but
maintaining the functionality of the "pango_markup" sway config command.
Deferred commands are only run once, during sway startup. This means
that deferring seat attachment based on whether we are reading the
config prevents devices from being reattached to the correct seat during
a config reload. Instead, only defer if the config is not yet active.
Fixes#6048.
This is my preferred terminal emulator now. Seeing as the default config
file is basically "Drew's preferences watered down a bit for a general
audience", I reckon it should be updated accordingly :)
Implements functionality described in [1]. Please see the issue for a
video with a demonstration of the new behavior.
An issue is that titlebars cover up a significant portion of the top
edge drop area. The solution is simply to change the edge drop area
hitbox to start at the contents instead of the container.

There was some unused code-paths for rendering surfaces with an
arbitrary rotation applied. This was imported from rootston.
Since we don't have plans to make use of this, remove it.
render_surface_iterator previously deduced the clip box from an optional
container passed with render data. This causes problems when offsets in
view geometry need to be compensated for in the clip dimensions.
Instead, prepare the clip box in render_view_toplevels where the offsets
are being applied, and compensate for them immediately.
A similar compensation is applied to render_saved_view.

These coordinates contain the all-time accumulated buffer attach point,
which is a way to perform incremental client-side initiated movement of
windows, intended as a way to maintain logical window positioning while
compensating for layout changes such as folding in a left side panel.
This value is not useful for implementing this feature, and break things
if they ever become non-zero. Their inclusion in calculations also tend
to cause confusion.
Remove usage of these coordinates, removing the ability for clients to
move themselves. This may again be supported if a better API is made
available from wlroots.
remove view from its own unmap event listener so when subsurfaces
link try to remove themselves they won't run into it.
This fixes the following ASAN use-after-free error on a build slightly
modified to instrument wl_list operations:

If any error is encountered during execution of the first subcommand of
a freshly created bar configuration, parsing apparently is to be aborted
and the current bar config is freed. The pointer to that memory is left
dangling though, leading to a use-after-free on successive bar
subcommands. This quite reliably ends in a crash like so:
sway -c reproducer.config
00:00:00.083 [sway/config.c:865] Error on line 2 'foo bar': Unknown/invalid command 'foo' (s)
free(): double free detected in tcache 2
00:00:00.608 [swaynag/swaynag.c:451] failed to register with the wayland display
Aborted (core dumped)
Minimal reproducer config:
bar {
foo bar
position top
}
Other messages:
malloc(): unaligned fastbin chunk detected
double free or corruption (fasttop)
The invalid command has to be the first for a newly created bar config.
Removing the command or switching order so it's not the first one masks
the problem.
Prevent this from occuring by resetting the pointer to NULL after
freeing the memory.

the original behavior set fullscreen for all descendents of a container,
which causes issues when firefox is one of those children because it
sends its own set_fullscreen request in response to being fullscreened.
Can be useful to make sure a bugfix is included. In the future maybe
the wlroots version string could include a commit hash when built
from source, too.
When a tiling container is floated, the focus stack needs to be
appropraitely modified to return the container to its original
position in the tree upon floating disable, like i3.
