The main reasoning behind double buffering was to avoid InternalWindow's
copy of m_frontBuffer detaching. But it already detaches when the qpa
calls blitImage(). So remove double buffering to simplify the backing
store.
While the GLFramebuffer::blitFromRenderTarget helper un-applies the transformations
the rendertarget has, the effect is not written with that in mind. In order to keep
it working properly, blit without any transformations and only adjust the coordinate
system difference between texture and fbo
Previously, we showed the window switcher even if there was only one
window, or no windows.
Now, we show the window switcher only if there are two or more windows.
Note that "desktop" counts as a window when the switcher's "show desktop
mode" is enabled.

Previously, we always added the desktop to the client list when the list
was empty. We added it even if the switcher's "show desktop mode" was
disabled.
Now, we only add the desktop to the client list if the switcher's "show
desktop mode" is enabled.
There are use cases for the headers to be used, e.g. when implementing
wayland-specific workflows from an Effect.
In order to be able to use these, we also need to expose libkwin to be
imported as it carries the interfaces' symbols.

Frame extents are written out over the wire they should be in X11 native
pixels.
i.e if we are using 200% scaling, and have X11 clients scale themselves
then from the point of view of the client reading the properties the
window decorations are twice the size as normal.

ScreencastStream is a C++ class, but we're having C style event handling
as static functions within the class. Mixing two styles within a class
isn't very clear.
We can turn them into normal methods with some thin wrapper functions
round the event handling.
Qt6 documentation states:
"Note: When using this window in combination with QQuickRenderControl,
the result of this function is an empty image, unless the software
backend is in use. "
We support a mode of using openGL rendering but then exporting as pixmap
images for Aurorae. In this case we should simply grab data from our
FBO.

The event spy is removed when xwayland closed, but it's based on the
process not the wayland socket, so it can be temporarily out of sync.
There were no guards for the connection being null.
BUG: 471789
glCopyTexSubImage2D is super slow on Intel GPUs on wayland.
We have an existing method to read from the framebuffer that is used in
the blur and other effects.
Rather than creating a scratch framebuffer every frame we keep a cache
per window for the lifespan of the effect.

qPrintable creates temporary objects that are destroyed before
`xkb_keymap_new_from_names` is called. It's highly likely that the data
we pass to xkbcommon will be overwritten by random data by that point.
Fix that by storing values as QByteArrays just like
`Xkb::loadKeymapFromConfig` does.
