79bf1b7e34 widgets: Mark widgets as needing flush during painting
Except for the case of syncing in response to an expose event,
where the platform asked us to flush a specific region, we
should strive to only flush parts that have been repainted.

And we should flush those parts to their nearest native child,
instead of unconditionally flushing the root/top level widget
as well.

By allowing drawWidget to schedule the flush we automatically
flush the minimal region, to the right widgets.

271d3bae38 QGraphicsItem: mark GraphicsItemChange::ItemMatrixChange as deprecated
The enum GraphicsItemChange::ItemMatrixChange is deprecated since Qt4
times. The corresponding matrix functions were also marked as deprecated
in 5.13 but the enum was forgotten. Therefore also mark it as deprecated
so it can be removed with Qt6.

7cbe1ca33d CMake: Fix detection of debug_and_release for Windows builds
If Qt is configured with -release or -debug we must set CMAKE_DEBUG_TYPE
or CMAKE_RELEASE_TYPE, but not both.

This was broken by 82a2c7df which fixed the issue for iOS
simulator_and_device builds.

We have the following situation for both relevant CONFIG values:

                           debug_and_release  build_all
iOS simulator_and_device   unset              set
Windows -release           set                unset
Windows -debug-and-release set                set

Trivia: On Windows, when configuring with -release (or -debug) then
the *feature* debug_and_release is not set.
The *CONFIG* *value* however, is unconditionally set in
msvc-desktop.conf.

77de5a329c Long live QColorConstants!
QColorConstant is a C++11 version of Qt::GlobalColor, except that instead
of Qt::red being an enum, QColorConstants::red is an actual QColor instance,
a bit like in the Qt 3 days.

In addition, the SVG names that QColor understands are also available,
with the same values. Technically, when building a QColor from a color
name, QColor ignores casing and whitespaces; we stick to the SVG/CSS
official color names (which are lowercase), and prefix them with Svg
to clarify where they come from. For instance, note how SVG's gray
is not Qt::gray.

[ChangeLog][QtGui][[QColor] Added QColorConstants, a namespace
containing constexpr QColor instances.

wasn't possible with QMutexLocker (which is not movable).

97db8e04ac Port away from QMutexLocker in public headers
We can't use qt_scoped_lock/qt_unique_lock here, so port to
std::unique_lock and std::lock_guard for now.

This is in preparation of deprecating QMutexLocker in favor
of std::unique_lock and std::scoped_lock.

In QFutureInterface, change the return type of mutex() from
QMutex* to QMutex&, so we don't need to deref when passing
to std::lock_guard. We need to keep the old method around
for BC reasons, so the new one needs an artificial function
argument for disambiguation. This will vanish come Qt 6.

QT_AUTO_SCREEN_SCALE_FACTOR has the usability problem that it mixes
enabling the high-DPI scaling mode with the method of getting screen
scale factors (“auto”). Due to this, it ends up with a slightly
strange name.

QT_ENABLE_HIGHDPI_SCALING matches the C++ option
(Qt::AA_EnableHighDPiScaling), and leaves the scale factor acquisition
method unspecified, possibly to be set by some other means (like
QT_SCREEN_SCALE_FACTORS).

3e5362bfa1 HighDPI: Add “metrics” manual test
This test displays a summary of relevant DPI and scale
factor/devicePixelRatio values:

 - DPI and DPR as seen by the application
 - Input from QPlatformScreen
 - Input from environment variables.

900f2cb6f7 Update Dpi and scale factor computation
Remove pixelScale() in favor of logicalBaseDpi(). Compute scale factor
based on logical DPI and logical base DPI, or optionally based on the
physical DPI.

Add policies for running the scale factor and adjusting the logical
DPI reported to the application. The policies are set via environment
variables:

  QT_SCALE_FACTOR_ROUNDING_POLICY=Round|Ceil|Floor|RoundPreferFloor|PassThrough
  QT_DPI_ADJUSTMENT_POLICY=AdjustDpi|DontAdjustDpi|AdjustUpOnly
  QT_USE_PHYSICAL_DPI=0|1

dd9da0441b Compute logical DPI on a per-screen basis
The logical DPI reported to applications is the platform screen
logical DPI divided by the platform screen scale factor.

Use the screen in question when calculating the DPI instead of
the values from the main screen.

QHighDpiScaling::logicalDpi now takes a QScreen pointer.
