Summary:
When a window is being interactively resized, its contents may jump. The
reason why that happens is because KWin renders partially resized client
window. Composite extension spec says that a window will get a new pixmap
each time it is resized or mapped. This applies to the frame window, but
not to the client window itself. If the client window is resized,
off-screen storage for the frame window won't be reallocated. Therefore,
KWin may render partially resized client window if the client doesn't
attempt to be in sync with our rendering loop. Currently, the only way
to do that is to use extended frame counters, which are not supported by
KWin.
So, in order to fix visual artifacts during interactive resize, we need
somehow forcefully re-allocate off-screen storage for the frame window.
Unfortunately, Composite extension doesn't provide any request to do
that, so the only option we have is to resize the frame window.

Summary:
QDateTime::fromMSecSinceEpoch uses Qt::LocalTime by default. This involves an
expensive localtime conversion. So instead force things to use UTC, as there
is no need for timezone information when tracking durations.
This is especially noticeable on Bedrock Linux, which uses a Fuse mounted
/etc, which is slower than a plain /etc and causes quite some slowdown there.
See https://github.com/bedrocklinux/bedrocklinux-userland/issues/140 for
details.
Test Plan: The screenedge unit test still passes.

Since we send the initial configure event after placing xdg-popups, we

We duplicate ping code in a few places. This change introduces a dedicated
method for sending ping events to an xdg-toplevel. In long term, it can be
used for sending "test" ping messages at random interval.

Summary:
If a client has been resized, it doesn't necessarily mean that the
decoration theme will schedule full repaint of the window frame. In
OpenGL and Xrender scene, we have a little hack that forces a full
repaint of window borders. However, we don't have one in QPainter
scene which causes all sorts of weird looking artifacts when resizing
a server-side decorated client.
We could add yet another hack in the QPainter scene, but a better
approach to tackle this problem would be to make DecoratedClient
schedule a full repaint of the decoration. It makes code in scene
plugins more straightforward and prevents us from repeating the same
mistake again.
Test Plan:
No longer able to see invisible decoration borders when
using QPainter render backend.

If the listed interpreter does not exist, kconf_update skips the update.

Summary:
According to the xdg-shell spec, configure events carry the maximum
window geometry size. If a client wants to enforce aspect ratio, it
may attach a buffer with smaller size. We need to account for that
when determining frame geometry in the commit handler.
I'm targeting 5.18 branch.

Currently, the input geometry for client-side decorated clients matches
the frame geometry, which makes it impossible for a user to resize such
clients by just dragging invisible area near window borders.

Prefer qobject_cast<> over Toplevel::isClient() because it's more type

This doesn't match kwin's concept of the default and so we just fail to
