Although not idiomatic, the pattern

was actually correct. Move to the idiomatic erase pattern

The example still has memory problems all over the place on

Given that there is only one mouse (which might change some day, but
hasn't yet), there can only be one window containing the mouse,
regardless of which screen it's on. The implementation before was only
able to send enter/leave events when moving from one window to another
on the same screen; but we need the enter/leave events to be sent when
moving between two full-screen windows on two screens as well.
Also send an enter event the first time the mouse moves, to whichever
window that happens to be. A Wayland compositor that renders its own
cursor will need to know which screen is in use at the beginning.

The fromUcs2() named ctor is designed to replace all the non-char
integral-type constructors of QChar which make it very hard to control
the implicit QChar conversions, which have caused a few bugs in Qt
itself. As a classical named contructor, it simply returns QChar.
The fromUcs4() named "ctor", however, needs to expand surrogate pairs,
and thus can't just return QChar. Instead, it returns a small struct
that contains one or two char16_t's, can be iterated over and be
implicitly converted to QStringView. To avoid bikeshedding the name
(FromUcs4Result, of course :), it's defined inline and thus can't be
named outside the function. This function replaces most uses of
QChar::requiresSurrogates() in QtBase.

There are (at least) two implementations of the low-level case-folding
algorithm, one of which (for QChar::toLower()) seems to be wrong (it
doesn't deal with special cases which expand to more than one code
point).
The algoithm hidden in QString and entangled with the QString
detaching code makes reusing the code much harder.
At the same time, the dependency of the algorithm on the unicode
tables makes exposing a non-allocating result type in the public API
hard. std::u16string would be an alternative if we can assure that all
implementations use SSO with at least four characters.
So, for the time being, leave this as internal API for use in an
upcoming QStringView::toLower() as well as case-insensitive hashing.

In 10.15 it's not working anymore and we have to properly fix

but QCocoaDrag::drag is expected to be blocking so we have to
add a nested event loop to emulate the old behavior. Dragging
