When GPUs are barely loaded, render times can spike randomly, likely because it goes
to a lower power state and has to ramp up again when KWin renders. To ensure this
doesn't make KWin drop frames, assume rendering always takes at least 2 milliseconds
Due to some misinterpretation of mode timings, the old method calculated vsync, not vblank,
so the resulting duration was much shorter, which caused frame drops on some systems.
BUG: 482064
When a key is pressed the string that should be used in the key event
changes depending on the xkb updated state for composed keys.
The key itself should be not be affected.
In the codepath to keep xwayland notified of key presses we have to
check the focussed window is not already an xwayland client. To avoid a
null dereference a guard is added that the focussed window is not null,
however the current code incorrectly returns early intead of skipping
just the relevant check.

This is to help to fix maximized xwayland windows not covering the whole
work area. Size hints are obeyed only when restoring the window.
According to the net wm spec, the window manager should not obey size
hints when maximizing a window and some other window managers already ignore
them when maximizing windows.

Currently desktop grid view is missing the selection rectangle when hovered over a desktop.
This adds the selection rectangle on hover, since it used to be there before three-state design.
Currently selected desktop has thinner and different colored border.
BUG:481812
The end render timestamp can be slightly in the past before the start
render timestamp. This results in negative render times, which can make
kwin wait way more than just one vblank interval before starting the
next frame.
It appears that there is no way to detect if the gpu has performed a
disjoint operation in OpenGL. It's available only in GLES. As a way
around, this change makes the GLRenderTimeQuery insert two probes: one
queries gl timestamps when starting rendering and ending rendering;
another one just queries std::steady_clock before and after painting.
This hardens the GLRenderTimeQuery against OpenGL providing nonsensical
results sometimes.

We know that org.kde.breeze.desktop is invalid as LayoutName for the
tabbox, it will break the default button in the tabbox kcm.
Also the DesktopListLayout and DesktopLayout aren't valid anymore
BUG:481640
Now that we have Wayland around, there's a whole branch of dependencies
that shouldn't be necessary anymore.
This allows to build KWin without all of it, allowing us to have a much
more compact alignment for cases where all the legacy software isn't
necessary anymore.
Bundle KWindowSystem X11-specific headers into it too, since it's part
of the same process.

It reduces the amount of manual OpenGL code, and it's better to use
ImageItem because that way the ItemRenderer will take care of snapping
to the pixel grid or colorspaces.

It's needed to properly render transformed overlay items. Ideally, the
ItemRenderer would split items that can be rendered with and without the
scissor test on its own. But we are not there yet, so pass the
PAINT_SCREEN_TRANSFORMED flag to force the ItemRendererOpenGL to use
hardware clipping.
