Corner buttons (WINDOW_MENU and CLOSE) are one more level down in
the scene-tree (see add_scene_button_corner() in ssd_part.c).
This fixes a minor issue where, when right-clicking on the CLOSE
button, the client-menu would be displayed in the wrong location.
... and use Title for the Drag (Move) and DoubleClick (Maximize)
titlebar actions, which are unexpected when the cursor is over one
of the window buttons.
Before this commit the window title could overflow in certain conditions,
usually when rapidly resizing. This commit fixes it by completely hiding
the corresponding scene node when there is no space available.

This matches the behavior of the surrounding borders and will usually
cause resizing instead of triggering the button itself. This effect
is only really visible when using a border width settings of > 1.
Fixes#379
As it turns out the reason for the workaround was a bug
in wlroots which got fixed in the meantime.
So to keep things simple just revert the workaround and
depend on the wlroots fix instead.
To update the wlroots subproject use
meson subprojects update wlroots
This reverts commit e87aa19066.
wlr_scene_buffers need an additional wlr_scene_buffer_set_source_box()
to be scaled correctly by wlroots based on the output scale.
With this commit the buffers are now scaled correctly but, especially
on higher scale factors, may be a bit blurry.
In the future we likely want a dynamic font label generator based
on the maximal scale of all the outputs the specific buffer is currently on.
Some inspiration for that could be
