src/xdg-popup.c: choose output depending on xdg-positioner
wlr_popup->current.geometry.{x,y} are usually zero on initial commit, so
xdg-popups were always unconstrained against the output which contains
the top-left of the parent toplevel.
This commit changes xdg-popups to be unconstrained against the output
which contains the top-left of preliminary popup geometry designated by
xdg-positioner given as an argument of "get_popup" or "reposition"
requests.
layer-shell: stop sending configure events on surface creation
With wlroots 0.18, layer-shell's new_surface event is emitted on
zwlr_layer_shell_v1.get_layer_surface request rather than the first
commit. This change layer-shell clients like fuzzel to flicker on launch
because labwc was sending a configure event with fullscreen geometry due
to the absence of geometry hints on get_layer_surface requests.
This commit removes the code that updates the usable area from
new_surface handler, preventing unintended configure events with
fullscreen geometry.
backend/drm: Implement support for renderer loss recovery
This implementation is nearly identical to Sway's, except that
it also reloads the configuration, to spur on reloading the
server-side decorations.
v2: Fix style.
v3: Add a reset to the magnifier.
v4: Oops, restructure reset handler a bit.
v5: Commit the magnifier reset immediately, before freeing the
lost allocator and renderer.
v6: Also check for failed render pass, which may return NULL.
v7: Add a second NULL test, just in case.

xdg: update initial maximize logic for wlroots 0.18
The initial configure event is now sent explicitly by labwc rather
than by wlroots. We need to move the maximize/fullscreen logic to
the initial commit handling accordingly.

view: implement `cascade` placement policy
Adds following settings:
<placement>
<policy>cascade</policy>
<cascadeOffset x="40" y="30" />
</placement>
"Cascade" policy places a new window at the center of the screen like
"center" policy, but possibly shifts its position to bottom-right so the
new window doesn't cover existing windows.
Currently, initially maximized (or fullscreen) xdg-shell views exhibit
one of two issues:
- some (e.g. GTK and Qt apps) paint an initial frame un-maximized
(before the "map" event) and only maximize in a later commit
- others (e.g. foot) maximize immediately without flicker, but never
store a valid natural size, so we end up using a fallback (640x480)
Under KWin, neither of these issues occur, so I looked into what labwc
is doing wrong. It seems that:
- wlroots internally sends an initial configure event with a size of
0x0 to all xdg-shell views. This requests the client to set its own
preferred (a.k.a. natural) size.
- For an initially maximized/fullscreen view, the initial configure
event should contain the maximized/fullscreen size rather than 0x0.
In labwc, this means we have to call wlr_xdg_toplevel_set_size()
earlier, i.e. from the new_surface event. Tracing with WAYLAND_DEBUG
shows that the initial configure event now has the correct geometry,
matching KWin behavior. With this change, GTK and Qt apps no longer
paint an incorrect un-maximized frame.
- However, this means that all xdg-shell views now suffer from the same
issue as foot, where we never receive a commit with the un-maximized
(natural) geometry. The correct way to get the natural geometry seems
to be to wait until we want to un-maximize, and send a configure
event of 0x0 at that point.
Sending a configure event of 0x0 when un-maximizing is a bit annoying as
it breaks some assumptions in labwc code. In particular:
- view->natural_geometry may now be unknown (0x0), requiring various
wlr_box_empty() checks sprinkled around. I added these in all the
obvious places, but there could be some code paths that I missed.
- Positioning the newly un-maximized view within view_maximize() no
longer works since we don't know the natural size. Instead we have to
run the positioning logic from the surface commit handler. This
results in some extra complexity, especially for interactive move.
See the new do_late_positioning() function in xdg.c.
Some TODOs/FIXMEs (non-blocking in my opinion):
- The view_wants_decorations() check is now duplicated in both the
new_surface and map event handlers. I'm not sure if this is necessary
but it seemed like the safest approach for now. More testing would be
nice, particularly with various combinations of config and client SSD
preferences.
- Aside from the interactive move case, the "late positioning" logic
always centers the view when un-maximizing, and does not invoke any
of the smart placement logic. If we want to invoke smart placement
here, I'd appreciate someone with more knowledge of that code to take
a look and figure out how to do that correctly.

xwayland: set initial geometry in map_request handler
Set the initial geometry of maximized/fullscreen views before
actually mapping them, so that they can do their initial layout and
drawing with the correct geometry. This avoids visual glitches and
also avoids undesired layout changes with some apps (e.g. HomeBank).
Fixes: #1320
v2: ensure valid geometry for unmanaged->managed case
Pango rounds glyph position and widths to nearest integer, which leads to
font dimensions jumping around when rendering with a scale, causing text
geometry to jump around when changing scale.
Disable this rounding to make the geometry stable.

package will be called once available. For previous packaging

src/xdg.c: verify source surface for xdg_activation request
wlroots < 0.17 didn't allow to reliably check the source surface of
an xdg activation request as it reset the surface to NULL when it
was destroyed before the token was used. This happens regularly for
notifications for example. Thus we treated the token as valid even
without checking for the source surface.
wlroots 0.17 added a new_token signal where we can attach information
to the existing token which we can then use when evaluating activation
requests. This patch implements that check.
I forgot to set session_lock_manager->lock, so it was always NULL.
This barely worked, but allowed multiple session-locks and conflicted
with comments in session-lock.h.
Before this patch, we were leaking memory [0] because the
shadow implementation did not free the ssd_parts on destruction.
There was also no check if shadows were actually enabled via
rc.xml or not so this also impacted people who were not using
shadows but were not setting the shadow size via their theme to 0.
[0] 44 bytes per ssd_part * 8 parts * 2 states == 704 bytes per
view closed. Note that Reconfigure also re-creates the SSD, thus
we were also leaking 704 bytes * nr_views per Reconfigure.

xdg: support xdg-shell v3 with popup repositioning
See https://gitlab.freedesktop.org/wlroots/wlroots/-/merge_requests/3514
which added support on the wlroots side.
We now re-run popup positioning (for both xdg-shell and layer-shell
popups) when the "reposition" event is received. This allows popups that
change size (such as qmpanel's applications menu) to be positioned
correctly.
xdg-shell v3 also gives the compositor some additional "hints" for popup
positioning (reactive, parent_size, and parent_configure_serial) which
are available but we don't make use of currently.

view: don't try to restore to very small width/height on unmaximize
Thonny (Python IDE made with Tk) may set the window geometry to 1x1 and
maximizes the window before mapping. This set `view->natural_geometry`
to 1x1, so labwc tried to restore the window geometry to it on
unmaximize, causing validation errors in `ssd_update_geometry()` as its
width and height are smaller than `LAB_MIN_VIEW_{WIDTH,HEIGHT}`.
This commit fixes it by not allowing geometries smaller than
`LAB_MIN_VIEW_{WIDTH,HEIGHT}` in `view->natural_geometry`.
