Currently, the shape region is not copied to the Deleted. If either
SurfaceItemX11 or SurfaceItemXwayland needs to build quads for a shaped
window, it won't be able to do so properly because the corresponding
x11 window is long time gone.
If the shape region changes before the window is unmapped, you may still
see visual artifacts. Unfortunately, the only way to fix that bug is to
switch to wayland.

This reverts commit 44ad9437c4 because it
breaks build:
platforms/x11/common/eglonxbackend.cpp:224:66: error: cannot initialize a parameter of type 'EGLNativeWindowType' (aka 'unsigned long') with an rvalue of type 'xcb_window_t *' (aka 'unsigned int *')
surface = eglCreateWindowSurface(eglDisplay(), config(), &window, nullptr);

It is perfectly valid to have a case where an item exists but has no
window. During these times the item will never be rendered.
Rather than guard in updateOffscreenTexture, it's more economical to
disable the frame rendering in the first place. Especially as then it's
easy to extend to item visibility.

Makes it possible to apply the dpms settings per screen instead of
applying it to all of them, which is wrong at many levels.
Will be even more important with other effects like rotation.
If kwin is explicitly restarted (kwin_wayland --replace) we reset the
crash count so that you can run it more than 10 times without exiting to
the logout screen.
Resetting to 0 causes a issue as that triggers ksplash to be shown
again.

We inintially created the wrapper to be light so avoided the QtCore
dependency and did it all in C.
In hindsight changing requirements means we want to add several more
features in here. The first step is to port to a more readable language
and toolkit.
Currently, the entire screen will be repainted when using the qpainter
render backend. With this change, kwin will repaint only the dirty parts
on the screen.
A better alternative is to return the damage region in the beginFrame()
function. This way, the render backend can force full screen repaints or
indicate what parts of the buffer needs to be repainted (for buffer age)
The main motivation behind the split is to simplify client buffer code
and allow adding new features easier, for example referencing the shm
pool when a shm buffer is destroyed, or monitoring for readable linux
dmabuf file descriptors, etc.
Also, a referenced ClientBuffer cannot be destroyed, unlike the old
BufferInterface.
If some popups of active window present, there was glitches on switching
such as stale popups or the popup happened below window.
Dismissing all the popups solves the problem.
