Add a coordinate scaling layer to QtGui, which supports 'devicePixelRatio'
type high-dpi on all platforms, in production and also for
development and testing purposes.
High-DPI scaling is opt-in, by setting environment variables:
QT_SCALE_FACTOR - sets a global scale factor
QT_AUTO_SCREEN_SCALE_FACTOR - sets per-screen scale factors,
where the scale factors are provided by the platform plugin.
This QtGui scaling can be used instead of or in addition to scaling
done by the window system. This distinction is not visible to
applications [when they use Qt API], which will see a change in
the value returned by the devicePixelRatio() accessors as usual.
Introduce a new (private to Qt) coordinate system: native pixels.
The coordinate system stack now looks like:
device-independent pixels (app, upper parts of Qt)
native pixels (lower parts of Qt Gui, platform plugins)
device pixels (backing stores and OpenGL)
Add private QHighDpi namespace with scaling functions that convert
between device-independent pixels and native pixels:
T toNativePixels(T, QWindow *);
T fromNativePixels(T, QWindow *);
Add scaling calls the QWindow (and friends) cross-platform implementation,
around the calls to QPlatformWindow functions. QPlatformWindow now uses
native coordinates - platform code remains largely unchanged since native
coordinates are window system coordinates.
QWindow now uses (possibly) scaled coordinates. This means that
platform plugins no longer can rely on QWindow::geometry() and
related functions. QPlatformWindow::windowGeometry() and other
convenience functions have been added for use when the platform
plugin needs to convert scaled geometry to native geometry.
Add Qt::AA_NoHighDpiScaling, which can be use to disable any
scaling in QtGui, effectively ignoring the environment variables.
(Note that this does not disable any scaling done by the window
system.)

Choose a scale factor that gives us more than enough
range.
The QPaintDevice::devicePixelRatio() convenience accessor

The common case of QVersionNumber is that there are few segments and
each segment is a small integers. So instead of allocating a
QVector<int>, just store those numbers in the class itself if
possible. Think of this as a "Small String Optimization" for
QVersionNumber.
QVector<int> costs 16 + 4*N bytes, plus malloc overhead. After this
change, QVersionNumber(5,4,0) will have an overhead of zero.
The memory layout is explained in the header. I've coded it so big
endian also works, but I have not tested it at all.
Aside from the special functions for QVersionNumber and operator>>, all
the rest of the algorithm could have been left unchanged. I only updated
segments(), normalized(), compare(), commonPrefix() and fromString() to
take advantage of the smaller implementation in a more efficient way.
Note: QVersionNumber's constructors often leave half of the object or
more uninitialized. That's not a problem.
