There is a misunderstanding of current blur protocol in the previous fix.
The update{Blur/Contrast}Region is only triggered by setting a new blur
object, which essentially ignore update the future update of blur
region.

This tries to restore the old behavior, by always creating a new blur
object, but always make sure we destroy them when being replaced.

BUG: 456442

Blur/Contrast object does not need to be re-created everytime install a new
blur. Otherwise blur/contrast object will be recreated everytime the window is
resized, which would cause leaking in both compositor and client.

Also, setRegion does not take over the ownership of wl_region, need to
destroy it afterwards.

The earlier code checked for that, that check got removed inadvertently

Also restructure code to always emit the result signal in case of errors

BUG: 454341

We obtain a wl_surface from Qt, create a KWayland::Surface from that only to then obtain the raw wl_surface from it

Skip the intermediate step

It is no longer used

The functionality has been added to kguiaddons directly

They are tied to the lifetime of the tiles, so don't also make it
managed by qApp.

Currently, the KWindowEffects API provides no any way to notify the
users that a particular effect has become unavailable.

This means that some effects may not work as desired when they are
enabled after starting plasma, e.g. panels may not slide, etc.

With this change, effect data will be re-submitted to the compositor
when the relevant globals are added.

ShmPool tries to resize itself when creating new images if the existing
allocated memory is too small.

As shadows currently use a single shared pool, this potentially happens
multiple times.

When an SHMPool is resized, the existing memory allocation is invalid
and all existing buffers have to be re-uploaded.  This patch introduces
one pool per tile, which alleviates that problem.

If you want git blame to ignore formatting revisions run:
git config blame.ignoreRevsFile .git-blame-ignore-revs

WaylandIntegration::self()->activation() will return null if the
compositor does not support activation. Any use must be guarded.

BUG: 440448

(With
frameworks/extra-cmake-modules!145
we have disabled the C and C++ specific compiler extensions.)

Allow the request to go through even when there's no surface.
Don't crash if we pass a nullptr QWindow.

Qt private headers don't have the dependencies they should have, hence
the solution is to explicitly add them.
