Summary:
QPainter doesn't render decoration shadows. It renders only
shadows provided through ShadowInterface.
With this change, painting of shadows is done in similar way OpenGL backend is
currently doing.
Before
{F5734867, layout=center, size=full}
After
{F5734870, layout=center, size=full}
Depends on D10811 (dummy decoration with shadows in autotests)
Test Plan:
* start kwin with QPainter backend enabled:
```
KWIN_COMPOSE=Q kwin_wayland --xwayland --windowed
```
* open konsole and kate:
```
DISPLAY=:1 konsole
DISPLAY=:1 kate
```

Summary:
KWin was quite good in ensuring that you don't need to install by
passing paths to the tests. The new way is much nicer, so code is
adjusted for the new way. Also if we require a newer ECM in future we
need to support the new way.
No guarantee that the tests don't pick something up from the system env,
that needs more testing.

Summary:
Under wayland we support high DPI putting by putting a separation
between the logical co-ordinate system and the resolution of rendered
assets.
When a window is on a high DPI screen, we should render at the higher
resolution.
Like the window scaling this handles any combination of a 2x scaled
decoration being rendered on a 1x screen or vice versa.
---
This patch is a bit different from the other scaling stuff. We have to
generate the quads *before* we have an updated texture with the new
scale. This means the scale isn't attached to the buffer like elsewhere.
That's why I added a property in TopLevel so there's still one canonical
source and things can't get out of sync.
BUG: 384765
Test Plan:
Crystal clear breeze and oxygen decos on my @2x display
Drag windows to attached @1x display, things still look OK when across 2
screens
Changing the scale of a screen updated the decos instantly

Summary:
Under wayland we support high DPI putting by putting a separation
between the logical co-ordinate system and the resolution of rendered
assets.
I didn't include window decorations in the previous wayland scaling
patchset. They were drawn them at a standard resolution, which is
implicitly scaled up.
This uses the Qt scaling, meaning oxygen and breeze (and others) get
perfect high DPI support with zero client changes.
Like the window scaling this handles any combination of a 2x scaled
decoration being rendered on a 1x screen or vice versa.
CCBUG: 384765
Test Plan:
export KWIN_COMPOSE=Q
Had two screens of different scales
It was the right size on both (as before)
Was super-sharp on the fancy screen

This change is similar to D7232 and moves the scene_qpainter into a
dedicated plugin. Compared to the XRender case it's more complicated as
the platform plugins need to implement a platform specific backend.
The base implementation for this part used to be in scene_qpainter. As
the idea is to completly move it away from KWin core it would be point
less to still have the backend definition in KWin core, but it cannot
be in the scene plugin as otherwise all platforms need to link the
plugin.
To solve this a new platformsupport subdirectory is added which contains
the scene platform backend as a static library. For the OpenGL scene such
a static library will also be required.
Test Plan: SceneQPainter test still passes, nested compositor still works
