d429146431 Keep tiled subwindow order on resize
QMdiArea::tileSubWindows() will move the active window to the first
position, in order to be consistent with other MDI applications on
Windows (according to the original commit message). However, the same
function is also used for re-tiling on resize, so we must make sure
to not reorder in that case.

720e243d88 Fix crash when detaching dangling QTextCursor
When a QTextCursor survives its QTextDocument, the internal
QTextDocumentPrivate pointer is set to null. There are checks for
this in all the QTextCursor functions to skip out early if such
a QTextCursor is used.

However, when executing the "if (d->priv)" condition in setters,
this will access the non-const operator->() of QSharedDataPointer
and detach the QTextCursorPrivate, and in the copy constructor of
this class, there was an unprotected call into priv->addCursor().

In theory, we could cast all the checks for d->priv to avoid
detaching, but in practice this doesn't matter, since the setters
will typically detach anyway later on.

[ChangeLog][QtGui][Text] Fixed a crash that can happen when calling
a setter on a QTextCursor after its QTextDocument has been deleted.

9601ad4e27 Fix font weights on macOS 10.14
On later versions of macOS, the font weight trait of fonts is a 64 bit
double, not a 32 bit float, and on macOS 10.14, CFNumberGetValue()
started returning false for values when the type conversion is lossy,
like it is documented to. Therefore, we would end up without weight
information in 10.14.

The fix is to ask for a double instead, which works regardless of
whether the CFNumber represents a 32-bit or 64-bit value.

7a6a9dbb7d QImageWriter: Fix default compressionratio
Before asking a image format handler to save an image, QImageWriter
sets the value of all supported options. For options like quality and
gamma, the default value is an illegal value (-1 and 0.0 resp.),
effectively telling the handler that the application has not requested
any particular value. But in the case of compressionratio, the default
was 0, a legal value. Fix by changing it to -1.

b4b706d454 Ensure that QTabletEvent is not pre-accepted before sending
In QWidget-world it's normal for input events to have the accepted
flag false by default, so that it's obvious after visiting a widget
subclass that does not override a particular handler function that it
did not handle that event type at all.  For tablet events in
particular, the contract (to which we've been paying more attention to
ensure that QTBUG-47007 remains properly fixed) is that if a
QTabletEvent is not accepted, a mouse event will follow.
Tablet-unaware applications need to get the same mouse events from a
Wacom stylus as they would receive from an actual mouse.

In this case the issue was missing hover events (mouse movements
in which no mouse button is pressed).  Without those, the enterEvent
and exitEvent virtuals are also not invoked properly.

6bb0cbc686 tst_QMdiSubWindow: fix flaky setOpaqueResizeAndMove test
tst_QMdiSubWindow::setOpaqueResizeAndMove checks if a resize of the mdi
subwindow works as expected by simulating mouse events. Those events are
sent to fast and therefore the operationMap of QMdiSubWindowPrivate is
not yet updated which let the test fail. There was already a call to
qWait(250) to wait for the 200ms timer but sometimes (esp. in virtual
environments) the timer was not triggered after this period.
Fix it by checking if resizeTimerId is set back to -1 which means that
updateDirtyRegions() was called.

6ff862a682 Fix binary compatibility with old generated moc files
Commit 1c623bc6d1 introduced a new
QMetaObject revision, which change the size of the QMetaEnum data.
When looking up QMetaEnum in a QMetaObject, this size need to be
checked for every different QMEtaObject from the hierarchy, not just
the first one.

5728a9d8a7 Windows QPA: Dispatch skipped touch/pen events if compression is off
If the hardware produces events faster than the app can consume between
two updates, Windows automatically coalesces them into a single message
with the latest touch/pen pointer state and coordinates, effectively
compressing those events. But the pointer API also supports querying
and retrieving the skipped individual touch and pen frames.

There are cases where keeping all the events generated by the hardware
is desired, especially for pen events where having the most sampled
points available is critical to precisely rendering curves.

Qt already defines application attributes to control event compression
for general high frequency events and for tablet events in particular.
Use them on Windows also to control whether to retrieve skipped frames.

[ChangeLog][Windows] The application attributes AA_CompressTabletEvents
and AA_CompressHighFrequencyEvents are now supported on Windows 8 and
above for touch/pen input, with the same defaults as on X11 (compress
touch events, don't compress tablet events)
