Child widgets should get the show/hide event when the TLW changes its
state, because child widgets are also visible or invisible. This
restores the Qt4 behavior (fixes the Qt4->Qt5 regression).
Restoring/minimizing the TLW now sends the spontaneous show/hide event.
Show events are now handled also in the expose event handler in the
QWidgetWindow class, because the show event must occur before the
expose event to avoid possible flicker e.g. the OpenGL content. This
can happen e.g. on XCB platform. If the "WindowStateChange" event occur
before the expose event (e.g. Windows platform) then the code in expose
event handler will be ignored to prevent event duplications.
Added autotest.

This reverts commit 90de48493be283b9afb249f6a0fd8dbd8958517d.
The call isn't necessary, but invokes undefined behavior.
It invokes undefined behavior because deleteTLSysExtra() is called
from deleteExtra(), which is called from ~QWidgetPrivate(), which is
called from ~QObject(). Thus, by the time we call q->windowType()
within setWinId(), q is no longer a QWidget, but only a QObject, and
calling a QWidget member function then is UB.
UBSan confirms:
qwidget_p.h:300:5: runtime error: downcast of address 0x2afdd4053620 which does not point to an object of type 'QWidget' (the Q_Q macro)
0x2afdd4053620: note: object is of type 'QObject'
qwidget.cpp:1712:93: runtime error: member call on address 0x2afdd4053620 which does not point to an object of type 'QWidget'
0x2afdd4053620: note: object is of type 'QObject'
It is also unnecessary:
deleteTLSysExtra() is called from two places: QWidget::destroy() and
deleteExtra(). deleteExtra() is only called from ~QWidgetPrivate()
which is only called from ~QObject() called by ~QWidget(), which,
however, already calls QWidget::destroy(). QWidget::destroy(), in
turn, unconditionally (for non-desktop widgets, at least) calls
setWinId(0) itself.
So fix the UB by removing the call without replacement.

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.)

actually improve on readability.
But the main reason is that something that's not supposed to be

This is not an attempt at converting all qWarnings() to printf-style,

The logic for handling cancel operations was spread out through

A new QKeySequence::StandardKey has been added for the Cancel sequence,
which maps to Escape on all platforms, and Command+. in addition for
OS X. The hard-coded logic in QWidget and subclasses for dealing
with closing the dialogs has been replaced with this key sequence,
which allows clients to override the behavior. Note that the widget
code is not wrapped in checks for QT_NO_SHORTCUT, as we don't care
about keeping widgets building and working under that define.

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.)
