In case Xwayland does not use multiple buffers, the currently attached
buffer is going to be destroyed if the frame window is resized. It may
render the previous and the current window pixmap invalid and thus result
in visual artifacts when an X11 client is being interactively resized.
In order to avoid the visual artifacts, this change disables support for
synchronized resizing for X11 clients if the version of Xwayland is less
than the version in which Xwayland started using multiple buffers, i.e.
1.21.
Differential Revision: https://phabricator.kde.org/D29250
Given that we now query the current X11 time stamp on Wayland, we can
enable synchronized resizing for Xwayland clients.
Differential Revision: https://phabricator.kde.org/D29250
Assume that Xwayland's current X11 time stamp corresponds to the system
monotonic time. Unfortunately, we cannot make roundtrips to Xwayland and
we cannot query the time stamp asynchronously because it may introduce
regressions in the standalone X11 window manager.

Disable screen edge modification, but allow the user to open an edge context menu and see the settings.
To set an edge immutable, just add `[$i]` right after the entry in `ElectricBorders` group, although the edges settings are shared between some `[Effect-something]` group under the key `BorderActivateSomething`.
Since one entry like `BorderActivateSomething` lists all edges that use this effect, it doesn't make sense to set it immutable.

Summary:
The screenshot made on screens with scale factor were downscaled by their scale factor making them blurry.
It prevents taking screenshots of missing Hidpi related bugs showing the issues under Wayland.
This fix the case of a single screenshot, but not the rest:
Multiscreen screenshot downscales the screen using scale factor.
Spectacle rectangular selection screenshot is broken as soon as some scale factor different than 1 is used on any screen.
Test Plan:
Under Wayland with a scale factor on a screen, take a screenshot using spectacle.
The output image is not downscaled and has the same size as the screen resolution.
No other change to any other screenshot mode, or under X.

The method paintSimpleScreen is responsible for redrawing the parts of
the back-buffer that need updating using the buffer_age extension.
The method fails to set correctly the damaged_region if, for some
reason, one frame needs a repaint of the whole screen. In this case
the backbuffer will request a full-screen repaint at some future
frame, so the dirty region will be extended to full-screen. However,
in this case the repaintRegion is not subtracted from the
damaged_region (as it is done for the non fullRepaints case below
--see the comment below--) and the damaged_region is reported to be the full
screen again. This causes all the subsequent frames to be reported
with a full screen damage, which causes some penalty, until
paintGenericScreen is invoked for some reason and then the damage gets
reset correctly.
We now set the correct damage and prevent falling into the fullRepaint
loop.
