0dda9dc7d0 Use namespace kwin only in autotests
In kwin core, we prefer not to put `using namespace KWin` because it
makes defining forward declared classes more trickier.

1fb9f6f13a Switch to SPDX license markers
The main advantage of SPDX license identifiers over the traditional
license headers is that it's more difficult to overlook inappropriate
licenses for kwin, for example GPL 3. We also don't have to copy a
lot of boilerplate text.

In order to create this change, I ran licensedigger -r -c from the
toplevel source directory.

8cedb797f9 Port DesktopGrid QtQuickWindow to EffectQuickView
Summary:
Lots of red, does the same thing in a simplified way avoiding creating a
real window and having to hack round it.

Test Plan: Click add and remove, remove button disables appropriately

aedc9e62e6 [effects] Forward wheel events
Summary:
Effects::checkInputWindowEvent(QWheelEvent *e) existed but it was not
hooked up to anything and would never be called.

This patch adds the relevant handling in the wayland filter, X filter so
the existing method gets called.

EffectQuickView is updated to handle wheel events.

Test Plan:
Used a ListView via an EffectQuickView in an effect.
I can now scroll with the mouse.

20a202b11a [libkwineffects] Construct correct mouse event when forwarding to QtQuickView
Summary:
Original code (copied from Aurorae) created a QMouseEvent for
QHoverEvents. Whilst it apparently worked, it's technically wrong.

It's safer to have an explicit type check given we come from a downcast
QEvent* and then build the correct event.

Test Plan: Hovered some icons

40b0296d5c [libkwineffects] Introduce API to easily show a QtQuick scene in an effect
Summary:
EffectQuickView/Scene is a convenient class to render a QtQuick
scenegraph into an effect.

Current methods (such as present windows) involve creating an underlying
platform window which is expensive, causes a headache to filter out
again in the rest of the code, and only works as an overlay.

The new class exposes things more natively to an effect where we don't
mess with real windows, we can perform the painting anywhere in the view
and we don't have issues with hiding/closing.

QtQuick has both software and hardware accelerated modes, and kwin also
has 3 render backends. Every combination is supported.

* When used in OpenGL mode for both, we render into an FBO export the
texture ID then it's up to the effect to render that into a scene.

* When using software QtQuick rendering we blit into an image, upload
that into a KWinGLTexture which serves as an abstraction layer and
render that into the scene.

* When using GL for QtQuick and XRender/QPainter in kwin everything is
rendered into the internal FBO, blit and exported as an image.

* When using software rendering for both an image gets passed directly.

Mouse and keyboard events can be forwarded, only if the effect
intercepts them.

The class is meant to be generic enough that we can remove all the
QtQuick code from Aurorae.

The intention is also to replace EffectFrameImpl using this backend and
we can kill all of the EffectFrame code throughout the scenes.

The close button in present windows will also be ported to this,
simplifiying that code base.

Classes that handle the rendering and handling QML are intentionally
split so that in the future we can have a declarative effects API create
overlays from within the same context. Similar to how one can
instantiate windows from a typical QML scene.

Notes:
I don't like how I pass the kwin GL context from the backends into the
effect, but I need something that works with the library separation. It
also currently has wayland problem if I create a QOpenGLContext before
the QPA is set up with a scene - but I don't have anything better?

I know for the EffectFrame we need an API to push things through the
effects stack to handle blur/invert etc. Will deal with that when we
port the EffectFrame.

Test Plan: Used in an effect
