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.

The implementation now uses the relaxed-constexpr
qCountTrailingZeroBits() function from QtAlgorithms, making the
QSizePolicy(Policy, Policy, ControlType) constructor constexpr on
C++14 compilers. The explicit check for DefaultType remains to keep
the constructor C++11-constexpr when called with just (Policy,
Policy).
Extend the constExpr tests a bit.

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.

Unfortunately, that ctor also takes a ControlType argument (defaulted),
and calls the non-constexpr, non-inline function setControlType().
In order to make at least the two-arg version constexpr, I added
a use of the ternary operator to check for type == DefaultType,
making all calls of the ctor that use type == DefaultType
constexpr. For init'ing an aggregate type without ctor in the
ctor-init-list, I needed to require uniform initialization, too.
C++11-style constexpr cannot call void functions, so I needed
to extract the transformation part of setControlType() into a
new function that returns the result instead of storing it directly.

In some situations, this allows for nicer code. It's also possible to
make this constexpr in C++11, whereas the mutable transpose() would
require C++14-style constexpr.
The new function should also be faster, since it just swaps the member
variables.
Because of constexpr-function limitations, the way the return value is
constructed needs to depend on the level of the compiler's C++11 support.
This is not the only class that requires uniform init to provide a fully
constexpr interface (QUuid and QBasicAtomic come to mind), so this should
probably be generalized across Qt at some point.

The new takeRow() functions return a pair of pointers to
QLayoutItems and, as the name particle 'take' suggests,
releases ownership of these layout items. Which in turn
means that the caller of the function is supposed to deal
with them.
This was not done here.
To fix, write a RAII class that takes ownership of the
returned layout items, deleting them when it goes out of
scope or gets a new value assigned (only move special
member functions are implemented, making the class move
-only).
Deleting the QLayoutItems is not so easy, though:
QFormLayout has a special function for clearing the
QLayoutItems out, so it appears that just calling their
destructors is not going to fly (though I don't know off
the top of the head why that should be a problem).
Solve this, for now, by adding the layout items back into
a temporary QFormLayout for destruction.

This caused a QEvent::UpdateRequest to be sent, which ended up in

The test passed on Windows since it contains one call to
QCoreApplication::processEvents() which causes the the initial WM_PAINT
