9a582f6dbe Remove unused method
Summary:
This isn't used and if it was would give the wrong value.
Actual correct size can be determined via Screens object.

Test Plan:
Grepped it's not overriding anything
Compiles

e90e596864 Add way to hide/show cursor in Platform
Summary:
Some platforms support to hide and show the cursor. This will be needed
by e.g. the zoom effect which currently only provides this functionality
on X11.

This change introduces a new method in the Platform to hide and show the
cursor. The methods need to be called balanced and the implementation
takes care of only showing again if all hide got matched by a show.

The actual hiding and showing is performed in the platform plugins. So
far the DRM and X11/Standalone platforms implement the required
functionality, though other platforms probably could implement as well.

997cf97c9f Atomic Mode Setting / Universal Plane preliminary support
This is Milestone 1 of full support of Atomic Mode Setting (AMS) and
Universal Planes in the KWin DRM backend.

With Milestone 1 we can use the primary plane of a DRM output and do an
AMS commit (this means mode setting aswell as page flipping), if the
driver supports it. Until now the functionality is only tested on Intel
graphics. You need the drm-next kernel for most recent DRM kernel
developments. As boot option set "i915.nuclear_pageflip". Additionally
at the moment AMS is still hidden behind the environment variable
KWIN_DRM_AMS. Set it, if you want to try out AMS.

What needs to be done next: Make it possible to transfer EGL buffers
directly to planes and implement logic for deciding about using a plane
or not for a specific buffer.

You can read more about it on LWN:

a67ccc3529 [platforms/drm] Pass ownership of gbm_device to Platform
Just like 4e7392b907:
the ownership of the gbm_device must be passed to the Platform as
the ownership of the EGLDisplay is also passed to the Platform and
we may not destroy the gbm_device for an EGLDisplay we are still using.

With this change I could restart the OpenGL compositor successfully
and switch from OpenGL 3.1 to OpenGL 2 without a crash or rendering
issues.

b5b2adc5a2 [platforms/drm] Only show cursor if a pointer device is available
Summary:
When the pointer device gets plugged off the cursor is hidden, when
a pointer device gets plugged in the cursor is shown again.

This allows to easily turn a tablet into a proper system by showing
the cursor only when it makes sense.

Test Plan: Tested on exopc with external mouse

2bff90976e Move backends/ to plugins/platforms/
Summary:
Source code reorganization:
The base class AbstractBackend got renamed to Platform, thus the
"backends" are "platforms" now. As they are plugins they should go
together with other KWin plugins which are nowadays in the folder
plugins.

So new location is plugins/platforms/
