Makes it possible to apply the dpms settings per screen instead of
applying it to all of them, which is wrong at many levels.
Will be even more important with other effects like rotation.
If kwin is explicitly restarted (kwin_wayland --replace) we reset the
crash count so that you can run it more than 10 times without exiting to
the logout screen.
Resetting to 0 causes a issue as that triggers ksplash to be shown
again.

We inintially created the wrapper to be light so avoided the QtCore
dependency and did it all in C.
In hindsight changing requirements means we want to add several more
features in here. The first step is to port to a more readable language
and toolkit.
Currently, the entire screen will be repainted when using the qpainter
render backend. With this change, kwin will repaint only the dirty parts
on the screen.
A better alternative is to return the damage region in the beginFrame()
function. This way, the render backend can force full screen repaints or
indicate what parts of the buffer needs to be repainted (for buffer age)
The main motivation behind the split is to simplify client buffer code
and allow adding new features easier, for example referencing the shm
pool when a shm buffer is destroyed, or monitoring for readable linux
dmabuf file descriptors, etc.
Also, a referenced ClientBuffer cannot be destroyed, unlike the old
BufferInterface.
If some popups of active window present, there was glitches on switching
such as stale popups or the popup happened below window.
Dismissing all the popups solves the problem.
BUG: 431046
If window quads need to be generated after the wl_surface is destroyed,
the SurfaceItemWayland::mapToBuffer() function will return wrong values.
In order to fix that, we need to store the last surface-to-buffer matrix
in SurfaceItem.
These appear to be remnants from a time where the current tabs were individual KCMs.
Remove some unneeded stuff and convert the only relevant registration to the normal K_PLUGIN_FACTORY macro
Since we adapted inputmethod to support methods like ibus, the input
method can be active but not have a visible panel.
This includes an extra property that will indicate us if the panel is
visible at any time. This will allow us to properly render the virtual
keyboard hide button in Plasma Mobile (or wherever we need it).
So far calling setActive(true) would issue a deactivation then another
activation. This sometimes makes maliit crash and we can achieve the
same result just by just issuing a reset.
Xwayland windows have two geometry types that are used during rendering
- wl_surface's geometry and x11 window's geometry. Unfortunately, it's
not possible just ignore the x11 window geometry because the window may
have a custom shape region. Pixels outside the shape region can have
arbitrary values; it's not guaranteed that the area outside the shape
region will be transparent.
In some cases, the x11 window geometry can be larger than the wl_surface
rect. That breaks repaint logic as the SurfaceItemXwayland can draw
outside the bounding rect.
Specifically, this issue can be seen while resizing Steam interactively.
Another example is where a video game enters fullscreen mode. I
occasionally see that Red Dead Redemption II window leaves a ghost after
itself when it switches to fullscreen mode.
It's not a perfect solution, but on the other hand, it doesn't look like
there's a better way to handle this due to the fact that there are two
conflicting geometry sources.
