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().

This change improves the loading speed of files stored in Android assets
folder by caching the information about files already opened.
Prior to the change, when creating a QFile or QFileInfo to an asset
file, the engine would first scan all the file's directory and parent
directories in order to cache all this in FolderIterator::m_assetsCache.
Due to the nature of Android assets, it might be very slow, depending on
the number of images in this tree.
In this patch, individual file accesses will stop using FolderIterator
and will simply open what is asked, caching the information about the
resource in order to avoid to have to call the expensive
AAssetManager_open if the file is accessed again (e.g. by QFileInfo).

transforming device independent window geometry to source geometry.
However, this assumption does not hold if/when we add support

the rhiFlush implementation.
Fix this by adding a sourceDevicePixelRatio argument to rhiFlush(),
which is set to either QWindow::devicePixelRatio() or
QWidget::devicePixelRatio(), depending on from where it is used.
Change deviceRect() and friends in qbackingstoredefualtcompositor.cpp

of a QWindow. Update call sites to use srouceDevicePixelRatio

to show how its oldCategoryFilter got initialized, which is what [22]
does. But it turns out the example code was crashy in any case, as it
left the oldCategoryFilter uninitialized (albeit probably null) until
the call to installFilter() had returned, and installFilter() calls
the new filter, so the new filter needs to check oldCategoryFilter
before calling it. The doc also failed to explain why it's OK to not
defer to the prior filter in these calls during installFilter(), so
revise the doc and example so that the latter behaves sensibly and
