Subject: [PATCH] Client: Don't send fake SurfaceCreated/Destroyed events
QPlatformSurface relates to the platform window, not the wl_surface.
The events are already emitted by QPlatformWindow on create/destroy.
To preserve compatibility for a previous KDE version it was faked to
emit the events when the wl_surface is created/hidden to keep behavior.
This is no longer necessary, and it has caused multiple errors, the latest
being a crash when switching between sub-menus with the Sway compositor.
[ChangeLog][QPA plugin] QWaylandWindow no longer sends fake SurfaceCreated/Destroyed events.
Use expose events to be notified when a Wayland surface appears.

Subject: [PATCH] Client: Fix scroll direction with touchpads
Wayland axis events and QWheelEvents are opposite way rounds. This was
handled for the case of discrete events, but not continuous events.
This leads to touchpads moving the wrong way round compared to other
clients.

Subject: [PATCH] client: Initialize mScale on creation instead of on show
At the time of creating a QPlatformWindow we will have a QScreen
assigned. It may not be the right one until we get a screen_entered
event, pointing instead to the primary screen.
When we get the screen_entered event we get the correct scale and call
handleWindowScreenChanged. However if it's the same screen as before
QWindowPrivate::setTopLevelScreen will no-op because from it's POV the
screen hasn't changed at all.
This leaves the window having the scale change without any notification.
This is notable with QQuickWidget which creates an FBO very early on
before the window is shown. This would then use the devicePixelRatio of
1 as it is currently unset and then not get any change notification.

Subject: [PATCH] Client: Make frame back callback timeout configurable
To avoid rendering when windows are minimized, we try to detect
this case by checking if 100 ms passes after an update before
any frame callback arrives. Wayland expects to drive the rendering
through frame callbacks, while Qt expects to be informed when a
window is no longer visible and will run a tight, vsynced render loop
until it gets the appropriate event. This mismatch causes issues,
and the timeout is an attempt to avoid actively rendering to a hidden
surface by detecting the missing callbacks.
It causes problems on embedded, though, when a device is so
busy that the timeout happens even when the window is visible.
So we introduce a way to configure the timeout. Either increase
its duration if you can guarantee a certain minimum time between
events even with high load, or set it to 0 to disable it completely.
(at the expense of drawing to invisible windows).
Note that this is required for fixing a critical memory leak that
happens when using Wayland on embedded.
This was mistakenly pushed to 5.12 branch, so it will not be
automatically merged upstream. Therefore we have to
cherry-pick it.
[ChangeLog][Client] Added support for QT_WAYLAND_FRAME_CALLBACK_TIMEOUT
environment variable, which can be used to disable or change the
internal frame callback timeout. If you see windows that stop rendering
or minimize on heavy load, then try setting the variable to 0.

Subject: [PATCH] Client: Send subsurface expose event when toplevel is configured
If a subsurface is set to be visible on the cilent side before the top
level is configured it will do not create an exposeEvent and map a
buffer as we fail the check in isExposed() where we check the parent.
This is correct behavior.
However, when the toplevel receives an applyConfigure from the shell
client we need subsurfaces to update accordingly.
This fixes a race where subsurfaces are not shown with slow compositors.
