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.
BUG: 481721
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.
The environment variable is primarily meant as a workaround for displays
and drivers that misbehave when more than 8 bits per color is used. To simplify
the code, this commit makes the environment variable only control the bpc
used for displays, instead of also controlling which buffer formats get
used.
The InputPanelV1Window doesn't actually need popupOffset(). Its popup
positioning is not data driven like xdg-positioner. It will be simpler
and more readable to compute the desired popup geometry explicitly.
The main motivation behind this change is to make the glide effect stop
setting a custom projection matrix in order to assist with making the scene
2d only.
The brightness of the screen is read from the luminance tag, and through
the color management protocol(s) passed to apps, so that they can adjust
their content accordingly
If the client is slow, kwin can receive _NET_WM_MOVERESIZE requests
after user has released mouse buttons. Ideally, the window manager
should refuse starting an interactive move/resize operation in such a
case so it's still possible to finish moving or resizing the window
by releasing mouse buttons.
If somebody else claims the selection, it's unclear what we should do.
kwin can't give up its selection as it's the one who is responsible for
window management and compositing. If anything, Xwayland should ensure
that no client can claim WM_S0.
Apparently, libepoxy requires a current EGL display in order to resolve
EGL functions. This is unexpected as most of the EGL functions require no
current opengl context.
This change makes kwin bypass libepoxy for problematic cases.

Quick tile mode reset should be done in the interactive move handler,
where the new move offset is set. Only reset it on resize to unsnap
the window from the tile.
