In rare cases, Workspace::restoreFocus() may fail, for example when the
most recently activated client is about to be destroyed or unmapped.
If it happens that we cannot restore the focus, then mark the window in
FocusIn event as active.
CCBUG: 424223
We may call setActive() on a window that is being deleted. We cannot
guarantee that at that moment the X11 window or the Wayland surface is
still valid. So, the best course of actions is to do nothing.
BUG: 424255
In order to ensure that no configure events will be sent before the full
initial state is committed, we need to queue maximize and full screen
requests or else the client may receive an "unexpected" configure event
and we miss to call initialize().
In most cases, we don't need to react to client geometry changes, but in
code that deals with server-side window decorations, we need to react to
client geometry changes. The problem is that frame and client geometry
updates are not correlated even though there is a connection between the
frame geometry and the client geometry.
This change introduces the client geometry in the Toplevel class in order
to allow monitoring client geometry updates from DecoratedClientImpl.
There are several ways to handle unmapping of a wl_surface. The first
one is to destroy the associated AbstractClient instance. The second one
is to transition the AbstractClient in a special state.
The problem with the second approach is that it makes animations such as
fade out more difficult to handle since effects in kwin are geared more
towards the first approach (destroying AbstractClient).
Summary:
This change splits the XdgShellClient class to better match existing
abstractions in the xdg-shell protocol and fix a few issues related to
sending configure events.
In the new client classes, configure events are handled differently.
Instead of blocking configure events, we try to send them as late as
possible. Delaying configure events will let us merge changeMaximize()
for X11 clients and Wayland clients and it also fixes the bug where
we don't send the final configure event when user has finished resizing
a window.
Given that configure events are not sent immediately, XdgSurfaceClient
keeps the last requested frame geometry and the last requested client
geometry.
This patch doesn't intend to fix all issues in kwin's implementation of
the xdg-shell protocol. For example, we still handle surface unmapping
very poorly.
Test Plan: Tests pass.

Summary:
Prefer virtual methods that take QRect and QSize rather than multi-int versions.
Makes for clearer API and reduces the amount of code that was taking all of the

We have duplicated code in InternalClient and XdgShellClient to create

introduces a method that AbstractClient subclasses can call to create
a window decoration.

Summary:
The new method provides a generic way for destructing clients. Notice
that we can't just delete clients because we may need to discard
temporary window rules, which is usually done in destroyClient().

Summary:
Currently, we have only one shell client type - XdgShellClient. We use
it when we are dealing with Wayland clients. But it isn't really a good
idea because we may need to support shell surfaces other than xdg-shell
ones, for example input panel surfaces.
In order to make kwin more extensible, this change replaces all usages
of the XdgShellClient class with the AbstractClient class.
Test Plan: Existing tests pass.

Summary:
Not all Client classes have support for the maximized mode. Therefore,
it can be made opt-in to reduce the amount of plumbed methods.
Unfortunately, there a few places, which don't have any connection with
the maximized mode, where AbstractClient::geometryRestore() is used, so
it cannot be made 100% optional at the moment.

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.

Summary:
So far the window geometry from xdg-shell wasn't implemented as it should
be. A toplevel must have two geometries assigned to it - frame and buffer.
The frame geometry describes bounds of the client excluding server-side
and client-side drop-shadows. The buffer geometry specifies rectangle on
the screen occupied by the main surface.
State and geometry handling in XdgShellClient is still a bit broken. This
change doesn't intend to fix that, it must be done in another patch asap.
Test Plan: New tests pass.

Summary:
In order to properly implement xdg_surface.set_window_geometry we need
two kinds of geometry - frame and buffer. The frame geometry specifies
visible bounds of the client on the screen, excluding client-side drop
shadows. The buffer geometry specifies rectangle on the screen that the
attached buffer or x11 pixmap occupies on the screen.
This change renames the geometry property to frameGeometry in order to
reflect the new meaning assigned to it as well to make it easier to
differentiate between frame geometry and buffer geometry in the future.

Don't put method definitions in the header file of XdgShellClient class
as it makes the code visually inconsistent. InternalClient is a good
example of how the header file of a subclass of AbstractClient class
should look like.
This change also cleans up the order of things in the header file, thus
making it a bit more obvious where new things should go.
Summary:
Rename ShellClient to XdgShellClient in order to reflect that it
represents only xdg-shell clients.
Test Plan: Compiles, tests still pass.
