Merge branch 'main' into push

If we treat the drag icon as distinct from other layers (it doesn't have
contents that are interactive, focusable, etc.), then we can iterate
over layers meaningfully with a simple for loop.

 ## Building dwl
 
 dwl has only two dependencies: `wlroots` and `wayland-protocols`. 
 
-Simply install these (and their `-devel` versions if your distro has separate development packages) and run `make`.  If you wish to build against a Git version of wlroots, check out the [wlroots-next branch](https://github.com/djpohly/dwl/tree/wlroots-next).

-To enable XWayland, you should also install xorg-xwayland and uncomment its flag in `config.mk`.

 ## Configuration
 
-All configuration is done by editing `config.h` and recompiling, in the same manner as dwm. There is no way to separately restart the window manager in Wayland without restarting the entire display server, so any changes will take effect the next time dwl is executed.

 ## Running dwl
 
-dwl can be run on any of the backends supported by wlroots. This means you can run it as a separate window inside either an X11 or Wayland session, as well as directly from a VT console. Depending on your distro's setup, you may need to add your user to the `video` and `input` groups before you can run dwl on a VT.

+to add your user to the `video` and `input` groups before you can run dwl on
+a VT. If you are using `elogind` or `systemd-logind` you need to install
+polkit; otherwise you need to add yourself in the `seat` group and
+enable/start the seatd daemon.
 
-When dwl is run with no arguments, it will launch the server and begin handling any shortcuts configured in `config.h`. There is no status bar or other decoration initially; these are instead clients that can be run within the Wayland session.

+decoration initially; these are instead clients that can be run within

-If you would like to run a script or command automatically at startup, you can specify the command using the `-s` option. This command will be executed as a shell command using `/bin/sh -c`.  It serves a similar function to `.xinitrc`, but differs in that the display server will not shut down when this process terminates. Instead, dwl will send this process a SIGTERM at shutdown and wait for it to terminate (if it hasn't already). This makes it ideal for execing into a user service manager like [s6](https://skarnet.org/software/s6/), [anopa](https://jjacky.com/anopa/), [runit](http://smarden.org/runit/faq.html#userservices), or [`systemd --user`](https://wiki.archlinux.org/title/Systemd/User).

-Note: The `-s` command is run as a *child process* of dwl, which means that it does not have the ability to affect the environment of dwl or of any processes that it spawns. If you need to set environment variables that affect the entire dwl session, these must be set prior to running dwl.  For example, Wayland requires a valid `XDG_RUNTIME_DIR`, which is usually set up by a session manager such as `elogind` or `systemd-logind`.  If your system doesn't do this automatically, you will need to configure it prior to launching `dwl`, e.g.:

 ### Status information
 
-Information about selected layouts, current window title, and selected/occupied/urgent tags is written to the stdin of the `-s` command (see the `printstatus()` function for details).  This information can be used to populate an external status bar with a script that parses the information.  Failing to read this information will cause dwl to block, so if you do want to run a startup command that does not consume the status information, you can close standard input with the `<&-` shell redirection, for example:
