All backends already have an init method so far called from the ctor.
This change moves the call to init out of the OpenGL backends and makes
it the responsibility of the creating code to also call init on the
backend.
This change makes it easier to have virtual methods being called during
the initialization.
The backend is prepared for managing multiple x11 windows. Currently
it's still only one window, but it's all internally working through
the architecture for multiple windows.
For this AbstractBackend has a new virtual screenGeometries() method
which returns a QVector<QRect>. By default it's just one QRect at 0/0
with the size of the one screenSize().
The last stage for window rendering is triggered by
Scene::finalDrawWindow. Adding a security check there if screen is locked
no non-lock screen window should be rendered.
Unfortunately this method is virtual so the check needs to be done in the
base and all implementing child methods (currently only OpenGL).

Most of those effects didn't need special screen locking handling on
X11 as they prevented screen locking. On Wayland though, we don't
want the lock screen shown on a cube.

the stackingOrderChanged() signal came before the window turned an effect window
usually this is no problem as the change shall not be caught anyway, but
the window may have changed its stack position

window wasn't correctly represented in
zoom, present windows and desktop grid effects
on the fly code streamlining:
- logout and above windows were handled equally in different code paths
- windows were painted on 0 opacity instead of just aborting the paint
local semi-paintdata because PaintData isn't assignable
(const dptr, I think) and we're post freeze.

This is similar to the applications to start. That is the value of the
command line argument is interpreted as a command to start.
The difference is that when this application exits, KWin will also quit.
The argument is so to say interpreted as a session.

We need to update the pointer position, also if the screen is locked.
Otherwise the pointer doesn't move on the locked screen with libinput.
In addition we need to use the m_globalPointer for finding the correct
lock screen window as updatePointerWindow also does sanity checking on
the coordinates.
Also we need to introduce security checks where we use the signal.

Ensures that all Wayland objects are destroyed and the cleanup handling
is performed before tearing down the Compositor. This fixes for example
a crash if a Surface with a Shadow is still around at tear down.
Eg. if a window is closed while "timeline.currentValue() == 0",
slotWindowClosed() will shortcut exit and not be removed from the
managers, thus dangle around forever.
Maybe there're other ways for a window to be deleted w/o
the closed slot being entered.

This allows to pin the focus on certain window as well
as to more easily give it away on others (typically launchers)

it seems we can "loose" focus reversions when the closing client hold a grab
(eg. the screenlocker or some games) thus we catch the typical pattern
(though we don't want the focus on the root anyway)

We use the hw module's backlight and set the color to either 0
or FF depending on whetehr we want to have the screen on or off.
This turns the backlight off properly. It is bound to the toggleBlank
functionality so that we always turn on/off the backlight depending
on whether our compositor is on or off.
In addition we listen to key release events on the power button to
toggle the state.

X11, Wayland, virtual, Framebuffer and hwcomposer have extremely
similar screens implementations. Let's add a base implementation
for them as a BasicScreens.
If we don't have a dedicated device identifier we should use the default
mechanismn which involves using the WAYLAND_DISPLAY or WAYLAND_SOCKET env
variable.
