By default, mobile browsers create a (layout) viewport
much wider than the visual viewport in order to be
compatible with web pages created with desktop browsers
in mind.
This means that the default view is zoomed out. This
zoom is not reflected in window.devicePixelRatio, and
Qt ends up setting the canvas render size to be larger
than actually needed.
The window.visualViewport.scale property reflects this
“mobile” zoom level: add it as a devicePixelRatio factor.
(The value will be less than 1 when zoomed out). User
pinch-to-zoom may change the zoom level and resize
the visual viewport; install a resize handler as well.
For now we limit the devicePixelRatio value in order
to avoid creating gigantic backing store images - this
is something we can revisit later on.

The logic is a bit involved in qmake.
The Qt internal qt_common.prf adds CONFIG += strict_c++ which applies
to qt modules, qt plugins, qml plugins, qt helper libs, winmain and
qt_apps, qt_tools, but NOT tests (which is important because the tests
on Windows MinGW fail to build without the GNU extensions).
Then default_post.prf checks for the strict_c++ value and either uses
the strict or non-strict C++ standard flags. default_post.prf is
loaded for all qmake projects, not just the Qt internal ones.
Now CMake doesn't provide a transitive based option to disable C++
GNU extensions with a mechanism similar to target_compile_features.
It only provides the CXX_EXTENSIONS property and it's associated
CMAKE_CXX_EXTENSIONS variable. We can't set the variable at a
directory scope, because that is too coarse grained.
So we rely on setting the property via a function in every relevant
qt_add_<target> function.
Now the naming of the function is weird.
We name the function as qt_internal_<...>, because it's not meant to be
used by Qt users.
We prepend an underscore to the name because we need to place it in
Qt6CoreMacros, so that the function can be called by
qt_add_qml_module which IS a public function.
That's because in Qt5 load(qml_plugin) was private API, but in Qt 6 +
CMake we decided to make qt_add_qml_module() as public API.

The operators were declared as friend function templates (so, free
functions in the Qt namespace). Unfortunately, the template argument
of the operators was also defaulted -- causing MSVC trying to
instantiate those functions at all times, causing interesting
recursive template instantiation errors (C2968). It's extremely
likely that we're facing a MSVC bug, but work around it by not
defaulting the template argument. This in turn requires to move
the function definition outside QList's definition, otherwise
an extern template definition (like the ones we have for QList<QPoint>)
would cause a template redefinition error...
