Fix the ARGB32 NEON-optimized drawhelpers so they also build on AArch64.
The RGB16 NEON-drawhelpers are not converted as they use more assembly.

Where, by dropping the << Q_FUNC_INFO in ostream-style qDebug(), only
a string literal remained, converted to printf-style qDebug() on the

The ifdef gave an impression of the code path being hit only when
texture-backed widgets are present and OpenGL-based compositing is
active. This is false. Asserting on having a context current is
wrong (as shown by autotests on the 5.6 branch).

Neither the default nor the eglfs-specific backingstore release the OpenGL textures
that are in use when render-to-texture widgets are involved.
The result can be fatal on embedded devices that run out of GPU memory at after showing
and closing dialogs and popups a certain number of times.

The __ARM_NEON is the standard define for NEON instructions support
__ARM_NEON__ is only legacy, and specifically not defined in
AArch64 builds, which causes us not to detect NEON support there.
The NEON assembler files doesn't build with AArch64, so the NEON
drawhelper methods must be excluded for now.

Shifting a signed integer that overflows is undefined behavior. All
masks were changed to unsigned in qRgb and qRgba. While the alpha value
is enough to fix the undefined behavior, Visual C++ generates slow
code if not all of those constants are unsigned.

Currently QOpenGLWidget and QQuickWidget do not support having native
child widgets inside the same top-level window. In some cases this is
inevitable, f.ex. multimedia may require native windows when used from
widget apps. winId() calls made for various (valid or invalid) reasons
are also problematic.
There are no blockers for supporting this setup, however. By storing
multiple texture lists (one for each subtree where the root is a
native widget), adding the missing markDirtyOnScreen calls, letting
each native widget access the correct texture list (i.e. the one
corresponding to its children) when they are (separately) flushed, and
fixing composeAndFlush() to take the update region and the (native
child) offset into account, it can all be made functional.
The change also fixes the issue of keeping GL-based compositing
enabled even after all render-to-texture widgets in the window become
hidden. Due to the changes of how such widgets are gathered,
composeAndFlush() is not invoked anymore when no such widgets are
discovered for a given native parent. This is great since having
compositing enabled infinitely is an issue for applications like Qt
Creator that implement certain views with QQuickWidgets but cannot
afford the cost of texture uploads in other places (e.g. for the text
editor) on slower machines.
The openglwidget manual test is greatly enhanced to test various
situations (MDI, scroll areas, tab widgets, QOpenGLWidget as native
child, QOpenGLWidget with non-tlw native parent, etc.)

The latter is much faster as it doesn't have to deal with
time zones.
This change handles the trivial ones: Either the call to
currentDateTime() is immediately followed by a call to toUTC()
or toTime_t(). The latter is much faster on UTC QDateTimes, too.

taken.

The default backingstore implementation is now cleaned for ES_2 ifdefs.
All the checks are now done at runtime and ES 3.0+ is included as well
for the efficient, QImage::copy()-less path.
For embedded a customized backingstore is used so the change has to be
done separately there.
This should result in a slight improvement for QOpenGLWidget/QQuickWidget
when running on GLES 3.x.

The glColorMask call was troublesome. In addition, the Qt::WA_TranslucentBackground
was misinterpreted and recommended misleadingly in the documentation. The hellogl2
example's --transparent argument was disfunctional in practice.
Replace glColorMask with glBlendFuncSeparate. The hellogl2 example and the docs are
now corrected wrt enabling semi-transparency in a QOpenGLWidget that is not a top-level
(which is the most common case).

Instead of trying to detect one bit and set another, let's just use the
bits from the x86 CPUID instruction on x86. This makes use of the full
64-bit space now.
Since MSVC doesn't like enums bigger than 32-bit, we have to store the
bit number instead of the actual bit value in the constant. For that
reason, I also renamed the constants, to catch anyone who was using them
directly, instead of through qCpuHasFeature.

In C++, type punning with a union is not allowed. It will result in
compiler defined behavior at best, and undefined behavior at worst.
Specifically, if QRgba64 is passed to a function by value, the different
members of a struct might be passed in separate registers. This means
that any write to the quint64 might not blank out the values of the
struct whenever the compiler looses track with TBAA.

Since this is not approximated accurately in the simple blending

engine supports higher accuracy, the simple blending routines for RGB30

the handlers' .pri files added $$PWD to INCLUDEPATH to make the files
self-contained when used externally, but this polluted the include path
of the gui module itself, thus hiding incorrect use of QPA includes.

Literals 1. or 0. have type double, but QGradientStop.first is qreal and
thus can be float depending on platform/configuration, making
qBound call invalid (qBound(0., qreal_value, 1.) for example).

Adds the drawHyperlink method so that clients can draw a hyperlink
pointing to the specified URL at the specified rectangle. That new
method is to be used by GraphicContext::setURLForRect implementations
that want to render anchors as clickable links in PDF documents.

Resolve ambiguity with function calls (due to double->float conversion),
use qreal where needed intead of explicit 'double'.

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.)
Contributions from Friedemann and Paul.
