Font hinting is done in the Qt coordinate system, and ends up
looking very wrong if the painter is scaled. Now that high-DPI
scaling is cross platform, we can move the responsibility for
turning off hinting out of the platform plugin.
Note that we cannot change our minds later, since Qt does not have
a reference to all objects that perform text layout. Therefore, we
turn off hinting if and only if there is at least one screen with
scaling enabled at application startup. If this is not good enough
for you, you should disable scaling and support resolution independence
manually.

identical or at least very similar (I tested Clang for ARM, MIPS and

Additionally, the output is also the same for GCC when using brace

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.)

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.

might be broken if fileName and uuid have an orthogonal
component, if you excuse my vector analogy.
2. To hash fileName and uuid, it concatenated the two,
causing a temporary QByteArray to be created just for
hashing its contents. That prevented marking qHash()
as nothrow.
Fix by using new QtPrivate::QHashCombine and adding
uuid to the list of fields compared in op==.

Using the approach we already do for some GLES 3.0 functions we can provide a cross-platform,
cross-GL-GLES wrapper for ES 3.0 and 3.1 functions too.
Applications only have to take extra care about the version requests (context version
and version directives in shader code), the rest of their code can stay the same across
desktop/mobile/embedded, even when ES 3 functions are used.
The new functions are placed to a new subclass which is placed between QOpenGLFunctions
and the internal QOpenGLExtensions. This is necessary because, unlike with QOpenGLFunctions,
there is no guarantee that these functions are always available in all configurations.
When running on desktop OpenGL, we resolve as usual. If the OpenGL version contains the
function in question, either in core or as an extension, it will all just work. This is
handy because it does not rely on 4.x extensions like GL_ARB_ESx_compatibility, and so
ES 3.0 functions will be functional on OpenGL 3.x systems too by just setting a 3.x version
number in the QSurfaceFormat.
We will no longer qFatal on broken systems where the driver returns a 3.0 or 3.1 context without
the corresponding functions present. Instead, we show a warning and gracefully fall back to
resolving as usual, via eglGetProcAddress or similar. For functions that are available in ES2 as
an extension this may just work fine.
Added also an example that runs identically both with OpenGL and OpenGL ES 3 and utilizes some
ES 3.0 features like instanced drawing.
