1fb9f6f13a Switch to SPDX license markers
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.

5d7e22e5dc Fix viewport on vertically stacked monitors
Summary:
We want to translate by the monitor position, so that needs to be
the negative of the position.

But Kwin/KScreen treats 0 as the top of all monitors. GL treats 0 as
bottom, so that all needs inverting.

Hence this should be a positive y value for the viewport.

BUG: 386099
BUG: 385655

Test Plan:
Had two monitors
Side by side was - fine
Stacked vertically - still fine

Modded X code to extend in y instead of x.
3 monitors worked fine.

Nested wayland only seems to support one screen?

2b196bfa29 Move the loadTexture for X11 pixmap functionality to the EglOnXBackend
Summary:
To use eglCreateImageKhr for an X11 pixmap we need an EGLDisplay created
for the same XDisplay as the X11 pixmap. This means if we created an
EGLDisplay for a GBM device, we are not allowed to load a texture from
the X11 pixmap and can result in a crash in the driver.

Similar in the nested X11 setup the EGLDisplay is created for the
rendering window, but the X11 pixmaps are from the Xwayland server KWin
started. They don't belong to the same windowing system.

This change addresses this problem by moving the loading of X11 pixmaps
from AbstractEglTexture to EglTexture of the EglOnX11Backend. Thus for
any usage on a non X11 platform we cannot hit the code path any more.
In addition the nested X11 platform can indicate that it doesn't support
it and thus also doesn't go through the code path.

Test Plan: Tested standalone and nested X11 platform

33dffc0fd7 Move the x11 plugin sources into a x11/windowed directory
Preparation step for having two x11 backends: the windowed for Wayland
and a standalone for kwin_x11.
