In a QGraphicsTextItem without a width yet, there's no need to do any
layouting. The use case is obviously items with an app-defined size,
not the default where text items adapt to their contents.
Results:
0.065 msecs to create a QGraphicsTextItem with some text (layouted)
0.036 msecs to set everything up in a QGraphicsTextItem with 0 width
QTextEdit was abusing the width 0 to mean "no wrap, width comes from
contents", but since the value -1 means that already in QTextDocument,
QTextEdit now uses a width of -1 for that meaning.

The BASE argument of qt_add_resources now denotes the root point of the

got passed to qt_add_resources.
Old behavior:
qt_add_resources(app "images"
PREFIX "/"
BASE "../shared"

Alias is "../shared/images/button.png", and pro2cmake generated
QT_RESOURCE_ALIAS assignments to fix this.
New behavior:
qt_add_resources(app "images"
PREFIX "/"
BASE "../shared"
FILES "../shared/images/button.png")
The alias is "images/button.png". No extra QT_RESOURCE_ALIAS assignment

QChar should not be convertible from any integral type except from
char16_t, short and possibly char (since it's a direct superset).
David provided the perfect example:
if (str == 123) { ~~~ }
compiles, with 123 implicitly converted to QChar (str == "123"
was meant instead). But similarly one can construct other
scenarios where QString(123) gets accidentally used (instead of
QString::number(123)), like QString s; s += 123;.
Add a macro to revert to the implicit constructors, for backwards
compatibility.
The breaks are mostly in tests that "abuse" of integers (arithmetic,
etc.). Maybe it's time for user-defined literals for QChar/QString,
but that is left for another commit.
[ChangeLog][Potentially Source-Incompatible Changes][QChar] QChar
constructors from integral types are now by default explicit.
It is recommended to use explicit conversions, QLatin1Char,
QChar::fromUcs4 instead of implicit conversions. The old behavior
can be restored by defining the QT_IMPLICIT_QCHAR_CONSTRUCTION
macro.

Remove QDestopWidget public header, simplify the implementation that
maintains a Qt::Desktop type QWidget for each QScreen, and turn
QWidget's initial target screen into a QScreen pointer.
QApplication::desktop() now takes an optional QScreen pointer, and
returns a QWidget pointer, so that applications and widgets can get
access to the root widget for a specific screen without having to
resort to private APIs.
QDesktopWidgetPrivate implementations to look up a screen for an index,
widget, or point are now all inline functions that thinly wrap
QGuiApplication::screens/screenAt calls. We should consider adding those
as convenience APIs to QScreen instead.
Note that QWidget::screen is assumed to return a valid pointer; there is
code that handles the case that it returns nullptr (but also code that
trusts that it never is nullptr), so this needs to be defined, verified
with tests, and asserted. We can then simplify the code further.

QQuickTextEdit already listens to the contentsChange signal and
invalidates the changed parts of the document as a reaction to this,
