By avoiding unneeded nested QPainters.
Crash was:
ASSERT: "s" in file /data/sources/qt/qt5/qtbase/src/gui/painting/qpaintengine_raster.cpp, line 2239
s was nullptr because the inner QPainter had called updateState(0), which is then dereferenced by the outer QPainter.

In the referenced bug report, dismissing a QFileDialog while the
Qt Virtual Keyboard was in use would result in a crash.
Dismissing a file dialog created with
e.g. QFileDialog::getOpenFileName() causes it to eventually be
destroyed. When this happens, it starts deleting its children. Each
child widget's destructor calls clearFocus(). In clearFocus(), there is
a block of code that emits QWindow::focusChanged(), passing the result
of focusObject() called on that widget's window.
QWidgetWindow::focusObject() could end up using itself as a fallback
focus object if it had no other focus objects (e.g. children) to use
instead, even though it was in the process of being destroyed; as were
all of its children. The Qt Virtual Keyboard plugin would then try to
use the focus object, even though it was in an invalid state.
To fix this problem, we return early from QWidgetWindow::focusObject()
if the window is in the process of being destroyed.

This is a followup to 77a8e90cdd which
didn't handle the case where no columns had been moved.
visualIndices and logicalIndices are empty until initializeIndexMapping()
is called, in which case appending is wrong.
As a result, visualIndex(i) would return -1 for the values over
those added by read(), and an assert would happen at painting time.
The fix is to leave visualIndices and logicalIndices empty if
they are empty already, leaving it to initializeIndexMapping()
to fill them later if necessary (e.g. when moving a column).

When a text block is empty, and we are adding preedit text to it,
we need to merge the format of the preedit text with the current
format of the cursor, otherwise we will use a default format and
then suddenly switch to the proper one when the text is committed.
The reason this becomes a bit complex is that there are no rules
preventing someone from using several ime attributes to specify
formats for isolated parts of the text, and no rules defining the
order of such attributes. So even if the common case is one
text format attribute for the entire string, we need to make sure
we also handle the other cases gracefully, e.g. when we are setting
different formats for different substrings and then providing these
out of order. To make sure we have these corner cases covered, we
also add a set of autotests.

If a floating QWidget has a parent on a different screen, its DPI was
still inherited from the parent instead of taken from the screen.
The only reason we did was in case there is a customDpi set.
(customDpi is a private thing that is only used in designer to change
the appearance of the previewed widget)
So instead of recursing into QWidget::metric for each ancestor, just
use a for loop to find if one parent has a customDpi. If no customDpi
is found, then return the DPI of the right screen.

Embeddeding a QWindow via QWidget::createWindowContainer() fails to
deliver the SurfaceAboutToBeDestroyed event. This breaks any OpenGL
or Vulkan based QWindow that releases resources upon this event, and
is particularly critical with Vulkan where the only way to do properly
ordered swapchain - surface cleanup is via this event.
In the non-embedded case close() eventually ends up in an explicit
destroy() in QWindow. In the embedded case destroy() only gets called
from ~QWindow. This then silently breaks since the subclass' reimplemented
event() virtual is not getting called anymore.
To remedy the problem, simply add an explicit destroy() to
QWindowContainer.
