03700500be Create Cursor instance through Platform
By default the InputRedirectionCursor is created and only the X11
standalone platform creates the X11 specific cursor.

This is a preparation step for moving the X11 specific cursor
implementation into the x11standalone platform plugin.

44843f462f [plugins/qpa] Support SharingPlatformContext on the existing eglSurface and eglconfig
Summary:
So far SharingPlatformContext was only used if the OpenGL context
supports EGL_KHR_surfaceless_context. If not supported, KWin tried to
create a context through the Wayland API. Unfortunately on hwcomposer
platform this results in a crash as libhybris only supports the init
of EGLDisplay for one native platform.

This change tries to also use the SharingPlatformContext if there is
an OpenGL context in general. It reuses the native EGLSurface created
for the compositing scene and makes its own OpenGL context current on
that surface, too. As KWin creates an FBO, it never renders to it, so
it shouldn't matter at all.

In order to prevent EGL_BAD_MATCH errors when making Qt's OpenGL context
current also the EGLConfig from the scene is used to create the context.

Test Plan: Tested on Nexus5 with qtvirtualkeyboard in KWin

9d7ef58b2b Support restarting the OpenGL compositor on Wayland
Summary:
KWin needs to support restarting the OpenGL compositor in case of a
graphics reset event.

On Wayland the tricky part is that the applications should not notice
this. Most importantly KWin cannot just destroy the EGLDisplay and create
a new one. But this is how a restart works: the complete compositor gets
torn down and recreated - including the EGLDisplay.

This change moves ownership of the EGLDisplay to the Platform.
The AbstractEglBackend subclasses query the Platform whether there is
already an EGLDisplay. Only if there is no EGLDisplay the EGLDisplay is
created and only if no EGLDisplay is registered with Wayland the bind
is performed.

Another change is regarding the destruction: the AbstractEglDisplay does
no longer unbind the Wayland display and does no longer destroy the
EGLDisplay. The EGLDisplay is destroyed by the Platform - so very late
on application exit. The Wayland display is unbound when the Compositor
terminates.

Test Plan:
Limited testing with the added auto-test. This one needs to
be extended to fully verify that OpenGL applications continue to work.
But this requires build.kde.org to support OpenGL on Wayland.

736d99fc6a Properly trigger repaint for sofware cursor
Summary:
When the cursor changes the old and the new cursor geometry needs to
be repainted. Also when the cursor image changes a repaint of old and
new geometry is needed.

To support this the current cursor geometry is tracked instead of just
the cursor position. From the cursor position it's not possible to get
to the cursor geometry once the cursor image or hotspot changes, thus
the complete geometry needs tracking.

7c822fadee Move the OpenGL unsafe check into the Platform
Summary:
A new virtual method createOpenGLSafePoint is added to Platform.
This is invoked through the Compositor with a PreInit and a PostInit
argument pre and post creating the SceneOpenGL.

The Platform plugin can implement this and use it for detecting whether
creating the OpenGL compositor on this platform crashed in the past.
Thus it's the base for the openGLIsBroken platform check.

The x11 standalone plugin is the first to implement this functionality
using the previous code which was designed for X11.

This also means that a crash of the OpenGL compositor during init on
Wayland won't result in OpenGL being disabled.

d15d3a5ff1 Provide functionality of CompositingPrefs through Platform
Summary:
CompositingPrefs is only relevant for X11 standalone. It had some
"hacks" to make it not block Compositing on Wayland. Thus it was in
its current form not really useful.

Now all the functionality is provided through Platform with a default
implementation which is sensible for Wayland platforms.

The X11 standalone platform implements the new methods with the
Wayland checks removed.

In addition all calls to CompositingPrefs now go through the platform
directly and CompositingPrefs is completely dropped.

c45942a70c Move requiresCompositing from Application to Platform
Summary:
This change reduces the windowing system specific code pathes. Instead
of checking whether we are on X11 or Wayland to decide whether
compositing is required, we just ask the Platform.

The default is true, only x11 standalone allows to not require
compositing.

e73a86d420 Create screen edge through the Platform
Removes a diversion between X11 and Wayland. The base class Platform
creates an instance of class Edge with plugin implementations being
able to create a different type.

The X11StandalonePlugin does that and creates a WindowBasedEdge. For
this the implementation of WindowBasedEdge is moved from screenedges
into the plugin.

Unfortunately an ifdef is needed to make the screenedge test still
work as expected. This should be improved in future, e.g. have a good
way to load the platform plugin from the tests.
