It's possible for a fullscreen xwayland view to be unmapped without
being destroyed. In this case, we need to update top layer visibility,
otherwise panels and the like will remain hidden.
Since unmap is always called before destroy, it's sufficient to do the
update only in view_impl_unmap() and not in view_destroy().
Adaptive sync logic needs work still, but I tried to minimize changes
to it since I don't have hardware to test it.
This commit adds `<windowSwitcher thumbnailLabelFormat="%T">` to configure the label text in each item in the thumbnail-style window switcher. Its format follows `<fields><field content="custom" format="">`.
This allows us to share common codes for dealing with osd items.
For example:
- Get the clicked osd item to focus its associated window
- Scroll the items when their total height is taller than output height
Before this commit, output transformations were not taken into account for
parcent-based osd widths like:
osd.window-switcher.style-classic.width: 80%
osd.window-switcher.style-thumbnail.width.max: 80%
Removing newlines in rc.xml and menu.xml caused parser error with
following content:

...though it is a valid XML.
Let's not do that. I moved `grab_file()` to `buf.c` and renamed it to
`buf_from_file()`, because it now directly touches `struct buf` and
I don't like having a source file only for one function.
The new `--keyboard-focus [none|on-demand|exclusive]` option (default:
`none`) allows to some keyboard controls in labnag:
Right-arrow or Tab: move the button selection to the right
Left-arrow or Shift-Tab: move the button selection to the left
Enter: press the selected button
Escape: close labnag
The selected button is highlighted with the inner 1px border. Maybe we can
instead use different colors for the selected button, but I prefer the
inner border for now because it doesn't require us to add new color
options or make them inherit labwc's theme.
The if-statement doesn't make sense, because `view_get_string_prop()`
never returns NULL. And if it did, it would cause segfault in
`osd_thumbnail_update()`.
This commit adds new theme options:
- osd.window-switcher.style-classic.item.active.border.color
- osd.window-switcher.style-classic.item.active.bg.color
These theme options configures the border/background of selected window
item in the `classic` style window switcher. Their default values are
identical to `thumbnail` style window switcher, which means the default
border color is now `osd.label.text.color` with 50% opacity and the
default background color is now `osd.label.text.color` with 15% opacity.
In 2ac4811, I was missing that windows can be tiled to "center".
As a result, after executing
`<action name="SnapToEdge" combined="yes" direction="left" />` against a
center-tiled window, `view->tiled` is set to `CENTER|LEFT`.
