Windows in workspace.clientList() are sorted in the map order. This
means that the minimize all script will try to activate the last mapped
window when unminimizing windows, which is a bit annoying.
This change ensures that the minimize all script doesn't activate wrong
window by minimizing and unminimizing windows in the stacking order.
It's not a bullet-proof solution though, but it should produce good
enough results.
This improves file organization in kwin by putting backends in a single
directory.
It also makes easier to discover kwin's low level components for new
contributors because the plugins directory may come as the last place to
look for. When one hears "plugin", the first thing that comes to mind is
regular plugins, not low level backends.
This ports the nested wayland platform plugin to the InputDevice
abstractions.
Some global handling logic has been simplified to make porting more
straightforward.
The main motivation behind this change is to prepare input abstractions
for virtual input devices so the wl_seat can properly advertise caps or
the cursor getting properly mapped/unmapped when a fake pointer is
added/removed on a system without a hardware mouse connected.
With this, there are three abstractions - InputDevice, InputBackend, and
InputRedirection.
An InputDevice represents an input device such as a mouse, a keyboard, a
tablet, etc. The InputBackend class notifies the InputRedirection about
(dis-)connected devices. The InputRedirection manages the input devices.
Such design allows to unify the event flow for real and virtual input
devices.
There can be several input backends active. For example, the libinput
backend and an input backend that provides virtual input devices, e.g.
libeis or org_kde_kwin_fake_input.
If an output is disconnected, the Workspace will update the
Toplevel.output property for all windows that are on that output, then
it will call AbstractClient::checkWorkspacePosition() to fix window
position.
That may result in some windows partially sticking outside visible area
because AbstractClient::checkWorkspacePosition() has no idea what output
the window was.
This change addresses that problem by delaying updating the
Toplevel.output property so AbstractClient::checkWorkspacePosition()
could pick better window placement.
The role of enabledByDefaultMethod was misinterpreted. It exists only
for kcms so they can display undetermined state. EnabledByDefault should
still be set to a valid value.
Currently, if an output is hotplugged, all windows will be scrambled,
which is highly annoying.
With this change, windows will stick to their outputs if an output has
been connected or disconnected.

Currently, AbstractClient::geometryRestore() is abused to put windows
back on their original screen. It makes window placement more complex
and it breaks restoring initially maximized windows.
It looks weird given the kind of visualization where this text is
displayed.

After the decoration is destroyed, we need to resize XdgToplevelClient
to ensure that the scheduled configure event will have correct size.
As is, xdg-toplevel configure events are delayed. When it's actually the
time to send a configure event, XdgToplevelClient will compute the
requested client size from the moveResizeGeometry().
If the moveResizeGeometry() still includes window decorations, the
window will get bigger.

For optimization purposes, kwin will ignore repaint regions scheduled by
invisible windows, e.g. hidden docks, minimized windows, etc.
The problem is that it sort of breaks w->addRepaintFull(). If a lot of
animation frames are dropped, for example due to heavy cpu load, the
sliding popups animation can jump from the middle of animation right up
to the end. It will schedule a repaint but it will be ignored.
In order to work around that issue, this change makes the sliding popups
effect schedule workspace repaints in postPaintScreen() to ensure that
the Scene will always repaint dirty regions.
Hopefully, this should fix bugs where auto-hide panels sometimes flicker
on Wayland.

Without spacing it is not immediately evident where a doc comment
ends and a new declaration begins. Adding a line of whitespace
makes everything more readable and easier to scan quickly.
Currently, input events can flow directly to input device handlers and
sometimes they go through the InputRedirection, which simply forwards
them to the corresponding input device handler.
