Destroy request is not specified for foreign toplevel manager and it
does not prevent the compositor from sending more events.
Libwayland would ignore events to a destroyed objects, but that could
indirectly cause a gap in the sequence of new object ids and trigger
error condition in the library.
With this commit waybar sends a `stop` request to notify the compositor
about the destruction of a toplevel manager. That fixes abnormal
termination of the bar with following errors:
```
(waybar:11791): Gdk-DEBUG: 20:04:19.778: not a valid new object id (4278190088), message toplevel(n)
Gdk-Message: 20:04:19.778: Error reading events from display: Invalid argument
```
This error occurs because of an incorrect assumption that the size of
the list of nodes that contains the focused window is the number of
windows in a workspace.
The windows in a workspace are stored as a tree by Sway, rather than a
list, so the number of windows has to be found by counting the leaves of
a workspace tree.
GDK Wayland backend can emit two events for mouse scroll: one is a
GDK_SCROLL_SMOOTH and the other one is an emulated scroll event with
direction. We only receive emulated events on a window, thus it is not
possible to handle these in a module and stop propagation.
Ignoring emulated events should be safe since those are duplicates of
smooth scroll events anyways.
Fixes#386
Previously we only checked when connecting to the server whether it had
the minimum required version but didn't act accordingly in the various
functions that use the functionality of later versions. If there were a
server in the wild, that actually would not have this functionality,
there would have been a crash. Fix this by checking the version before
using the functionality and gracefully abort it.
There was an update the of the toplevel manager protocol. Unfortunately,
there are no new interesting updates with regard to the taskbar
implementation. Nonetheless, update the protocol xml files to the latest
version so that the implementation is up-to-date.
While being there, also change the debug warning that is shown when
there is a version mismatch between the server and client version of the
protocol.
Speedup battery state update by only updating the battery list when we
get a CREATE/DELETE event in the directory or whenever we do a full
refresh on the interval.
These modules, unlike others, have no horizontal margins by default.
This means that they'll appear uncomfortably close together in any
config that puts them side-by-side. In general, the default style should
make configs with any module ordering look good. Add the same 4px
horizontal margins that other module have to these.
To preserve the current default appearance, exempt the workspace module
from a margin on the appropriate side when it's the leftmost or
rightmost module on the bar.
The current service doesn't play too nice with Sway when it is started
from [sway service](https://github.com/xdbob/sway-services).
Waybar is started before the system has a display.

Restarting the service after the system has been initialized works nicely,
so this restart rule should do the trick without tinkering with the
target.
