The WM_DISPLAYCHANGE message it sent when displays are added, removed,
or update their properties such as the scale/DPI.
We were processing this message as part of QWindowsContext::windowsProc(),
which meant that we would only react to display changes if there was a
QWindow on screen. Just creating a QGuiApplication was insufficient to
pick up changes to screens after startup.
In addition, despite being documented to post messages to child windows,
WM_DISPLAYCHANGE only ends up in top level windows. Presumably it's the
top level window's responsibility to post the message to child windows.
As a result, if a QWindow was a native child window of a foreign window,
such as in audio plugins being hosted in a DAW, we would again fail to
pick up display changes.
We solve both these cases by decoupling the WM_DISPLAYCHANGE handling
from QWindowsContext::windowsProc(), by creating a dedicated window
for listening to WM_DISPLAYCHANGE. This is similar to how we already
handle tray icons, power notifications, clipboard, etc -- the only
difference being that since purely HWND_MESSAGE windows do not
receive WM_DISPLAYCHANGE it's an actual invisible WS_TILED window.
This also lets us remove the workaround for QTBUG-79248, which was
doing screen updates in response to WM_DPICHANGED when detecting
that there were no QWindows.

As of Qt6, QList will assert that an insertion index is in range of
existing values. QBoxLayout interprets negative indices as "append at
the end". That part is covered.
Indices larger than the number of items in the layout would trigger the
assertion in QList, but after the insert method had returned. That would
make it hard to debug. This change asserts the index range before
inserting, thus making it easier to spot the problem.

androiddepployqt calls qmlimportscanner to find qml modules.
Due to an issue in a generator expression, CMake did not write out the
android default qml output directory to the deployment json file,
which in turn means that qmlimportscanner did not get that
information.
When the scanner scanned the sources, it found some relative imports
but couldn't find relevant qmldir files because they were in an
android-specific directory.
This caused warnings like 'qmldir file not found at /some/path'
repeatedly.
Fix the generator expression to use $<COMMA> instead of , so that the
genex condition is evaluated successfully and the extra qml import
paths are passed along to qmlimportscanner.

the print dialog will show the wrong page size and orientation, and the

The dialog always shows the wrong values for the page margins (only
available through the presets dialog), but the printer's values are not
overridden. Also, the print range is taken care of correctly by the code
further down in this function, irrespective of the printer's output

The QWSI APIs for reporting added or removed screens is not transactional,
so when several screens change at once Qt will see each screen change as
a separate state.
As a result, Qt, or the application itself, may react to the first of
many screen updates by moving a window to a different screen -- one
which is going to updated (removed) in the next iteration of QWSI
calls.
This caused trouble on macOS, where we use many different signals to
detect that the system has changed the screens, one of them being that
a window has been moved to a different screen.
In the scenario above, we would be in the process of updating screens
in response to the system going to sleep, which means all 3 connected
screens will be disconnected and replaced with one fake screen provided
by the system.
As we delivered the removal of the first QScreen, Qt or the application,
would respond by moving the window to one of the other two screens, which
in turn would recursively trigger another round of screen updates. This
round would then proceed to remove (and delete) all remaining QScreens.
When we then recursed back to the initial round of screen updates
we would continue iterating and operating on screens that had already
been removed, causing a crash.
Since we know that the screens will stabilize eventually, and that
QCocoaScreen has cached all info based on the displayId and NSScreen,
we can safely skip any recursive invocations of updateScreens().
