7459aabcac Dmabuf recovery on EGL reset
Summary:
The EGL platform might go away at any time through reconfiguration or because
of a graphic error. KWin then resets the graphics. The dmabuf implementation
must respect that and recover from a graphics reset by recreating all EGL
images for existing buffer.

This assumes that we won't change our graphics API mid-session and that
supported plane and modifier configuration stays constant.

In practise we remember all current dmabufs in a single map and only remove
them if the client did destroy the resource.

BUG: 411980
CCBUG: 413403
FIXED-IN: 5.17.2

Test Plan: Applied screenedge configuration without crash.

bebe81209c Port QPA away from Wayland
Summary:
So far wayland was used by internal clients to submit raster buffers
and position themselves on the screen. While we didn't have issues with
submitting raster buffers, there were some problems with positioning
task switchers. Mostly, because we had effectively two paths that may
alter geometry.

A better approach to deal with internal clients is to let our QPA use
kwin core api directly. This way we can eliminate unnecessary roundtrips
as well make geometry handling much easier and comprehensible.

The last missing piece is shadows. Both Plasma::Dialog and Breeze widget
style use platform-specific APIs to set and unset shadows. We need to
add shadows API to KWindowSystem. Even though some internal clients lack
drop-shadows at the moment, I don't consider it to be a blocker. We can
add shadows back later on.

7a3722b4f5 Switch to Q_ASSERT
Summary:
Switch to Q_ASSERT in order to make code a bit more consistent. We have
places where both assert and Q_ASSERT are used next to each other. Also,
distributions like Ubuntu don't strip away assert(), let's hope that
things are a bit different with Q_ASSERT.

Test Plan: Compiles.

Summary:
QRegion::rects was deprecated in Qt 5.11. It is advised to use begin()
and end() methods instead.

2c26215d7e Request a high-priority EGL contexts
Summary:
This patch implements using EGL_IMG_context_priority to request
high-priority rendering contexts if the extension is available.

EGL_IMG_context_priority is currently used in this fashion by
e.g. Android's SurfaceFlinger (RenderEngine.cpp) and libweston
(gl-renderer.c) and seems promising given this widespread
acceptance.

8ae37c420b Move SceneOpenGL into a dedicated plugin
Summary:
Unfortunately a rather large change which required more refactoring than
initially expected. The main problem was that some parts needed to go
into platformsupport so that the platform plugins can link them. Due to
the rather monolithic nature of scene_opengl.h a few changes were
required:
* SceneOpenGL::Texture -> SceneOpenGLTexture
* SceneOpenGL::TexturePrivate -> SceneOpenGLTexturePrivate
* texture based code into dedicated files
* SwapProfiler code into dedicated files
* SwapProfiler only used in x11 variants
* Safety checks for OpenGL scene moved into the new plugin
* signal declared in SceneOpenGL moved to Scene, so that we don't need
to include SceneOpenGL in composite

Test Plan: Nested OpenGL compositor works
