Since the g_signal_emit() is not at the very end of the function one of
the listeners might free the lockscreen widget when receiving the
"lockscreen-unlock" signal. Hold a reference to prevent being cleaned up
before being done.

It's a boolean, not a string

Harmless now but might prevent future errors

This will be moved into an indicator at a later point.

Fixes #20

The lock screen now shows the current time and on upward drag it
switches to the lock screen. The lock screen then shows a keypad to
unlock the screen.

Validating the entered pin will be done in a follow up patch.

TODO in future patches:
 - slide up lock surface when swiping
 - wiggle pane a little if swipe is too soft
 - alpha blend out lock screen surface

This on is in Adwaita so we don't need gnome-icon-theme.

Fixes #7 (when there's also gnome-terminal installed)

See https://github.com/swaywm/wlroots/issues/897 for details.

This allows us to run phosh with wlroots/rootston master

This makes them close when clicked outside a layer-shell surface

Binding to wl_seat breaks GTK+ input since GTK+ binds it as well.
Needs to be investigated.

We use the overlay level for the lock screen so it's above 'top' which
is currently being used for the menus (until they turn into xdg popups).

Together with the input-inhibit protocol this make sure neither clients
nor other shell surfaces get any input.

Switch to wlroots layer-shell instead of weston's private desktop-shell
protocoll.

If one only needs certain values others can be passed as NULL

Assume a panel height of 0 instead. This allows us to use it to setup
the panel itself.

This will usually not happen but it's better to be safe than sorry.

This in turn needs xdg_shell from wayland-protocols

This enables us to use translations

There's no point in translating the time value.
