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.
Otherwise we'll show a dangling cursor but otherwise the cursor will be
updated by other code paths, so we end up with a weird cursor in the
middle of the screen that doesn't move.
It is possible for updateOutputs to be called when a pageflip is pending.
Freeing a DrmOutput with a pending pageflip is not allowed (see ~DrmOutput assert - the page flip handler will be called on the freed memory, possibly leading to use-after-free).
This works around the problem by delaying the destruction with teardown().
BUG: 422460
In atomic setting mode, when external display tears down, it will blank
crtc with dump buffer by legacy api, then re-plug the external display,
the blank can not be removed. We think the blank is not needed in atomic
mode setting.

We don't need to bind disabled outputs to surfaces that overlaps them.
This prevents error down the line and warnings about ignoring surface.enter events with Qt.
BUG: 419749
In previous code we used to update/show cursor even when the pointer
device was present, e.g mobile device. Guard it behind the cursor
enabled check.

Summary:
AbstractOutput::name() behaviour is changed so that it matches the X11
behaviour, showing an identifier like "HDMI-0".
XdgOutput.name is set to this name.
XdgOutput.description is currently set to the manufacturer name and
model, but it's not exposed to Qt so we probably don't care too much.
This should fix plasmashell changing applets when switching between X11
and wayland.
Test Plan:
Relevant unit test
I still need to run it on my laptop.

Summary:
As is KWin only had 1 Cursor which was a singleton. This made it impossible for
us to properly implement the tablet (as in drawing tablets) support and show where
we're drawing.
This patch makes it possible to have different Cursors in KWin, it makes all the
current code still follow the mouse but the tablet can still render a cursor.
Test Plan: Tests pass, been using it and works as well as before but with beautiful tablet cursors.

Summary:
Currently, we have only one shell client type - XdgShellClient. We use
it when we are dealing with Wayland clients. But it isn't really a good
idea because we may need to support shell surfaces other than xdg-shell
ones, for example input panel surfaces.
In order to make kwin more extensible, this change replaces all usages
of the XdgShellClient class with the AbstractClient class.
Test Plan: Existing tests pass.

Summary:
The previous code uses a fixed version of GSLS which does not match our suported GL targets. We need both, using kwin's existing MapTexture framework we can achieve the same thing in a better way with less code.

as when I applied the patchset with the custom shader.

Summary:
In case the hardware is not able to rotate the output for the configured
rotation value do this rotation in a post-process step.
For that rendering the current view into a separate framebuffer bound to a
texture that then gets sampled to the default framebuffer in an additional
rendering pass through a simple shader rotating it.
This allows us to leave the Effects system and internal model-view-projection
matrix untouched. The rotation in the post-processing step is isolated.

Summary:
Planes might be able to do transformations without compositing required.
When changing the current transform try this with the primary plane. If this
fails fall back to no transformation at all through hardware and communicate
the fact and other information through some getters.
Also adds an environment variable to never do hardware transformations.
Test Plan: Compiles.
