916cfede05 ANGLE: Allow Windows Phone to communicate swap region
eglPostSubBufferNV is used to communicate the size of the window, as
otherwise there is no way for the renderer to know if the last frame was
rendered in landscape or portrait, causing rendering glitches when the
orientation changes. The rotation flags are utilized in a few additional
places now to fix some corner cases where the rotation was not applied.

This patch should be squashed into "ANGLE-Improve-Windows-Phone-Support"
during the next ANGLE rebase.

ea17cc0768 QColumnView: re-enable scrolling of the preview widget
For some reason, each column in a QColumnView is a QAbstractItemView,
*including* the preview widget's column. Unfortunately,
the preview widget's column class was not overriding scrollContentsBy,
so scrolling it had no effect.

A more comprehensive solution would be a major refactoring of the
code to make that column a plain Q(Abstract)ScrollArea, as it doesn't
need QAIV's APIs at all, but I don't want to change code and risk
breaking behavior.

Widgets can have the attribute Qt::WA_ShowWithoutActivating
set, which is forwarded to QWindow as a property
(_q_showWithoutActivating). Both The cocoa plugin and
the windows plugin check for this property before
activating a window upon setVisible, so lets do the
same for the iOS plugin.

Note that this is not the same as shouldAutoActivate, since
the window should gain focus like normal if the user
taps on it.

c4054ab1b7 ios: add fallback in QIOSFileEngineAssetsLibrary for loading assets from ALAssetsGroupPhotoStream
[ALAssetsLibrary assetForUrl:] will not load assets coming from ALAssetsGroupPhotoStream. Such
assets can be stored in the cloud and might need to be downloaded first. Unfortunately, forcing
that to happen is hidden behind private APIs ([ALAsset requestDefaultRepresentation]). So if
the user through QIOSFileDialog opens the photo stream folder and chooses a
photo inside it, QIOSFileEngineAssetsLibrary will fail loading it.

This patch implements a work-around that basically asks ALAssetLibrary to enumerate all assets
in the photo library, and stop once we find an asset with the correct url. At that point we also
have a pointer to a ALAsset that can be used for loading. This is off course a slow way of loading
an asset, but at least better than not being able to load it at all.

762d493990 cocoa: ensure app don't crash when receiving drag from other app
Change 939f21be53 introduced a crash when dragging data from
a 3rd party app into the app. Basically the current code assumed
that we always have QCocoaIntegration::instance()->drag()->currentDrag()
but this seems to only be the case if the drag was started by the
app itself.

The crash was found by testing the fridgemagnets example. Just
drag text from other app into the example to see it crash.

Also, refactored the cursor code into a separate method
to simplify code reading.

1c7e3a2a33 QShapedPixmapWindow: ensure we set a valid geometry
On touch platforms, QCursor::pos() will only be 'valid' when a
touch event has (at least once) been translated to a mouse event.
Currently this never happens in QtQuick since QtQuick always
accepts all touch events and performs its own translations.

So rather than setting the geometry of QShapedPixmapWindow from
QCursor directly, we instead base it on mouse events. This will
ensure that we never try to set the geometry of the window to
an 'invalid' value, which can cause a crash on platforms like iOS.

Note that we currenly miss an API in Qt to get the current
touch points. When that is in place, we can also set
a correct start position for the window before the
first mouse move event arrives.

3287e7a68a QGraphicsWidget: call normal "setParent" when setting a parent
QGraphicsWidgetPrivate::init had a special code path for setting
the item's parent. For some reason that code path caused the
ItemChildAddedChange notification not to be sent to the parent
element, which is wrong. Instead use the "normal" path, which is
what the QGraphicsItem constructor does anyhow.

ec73b5d4b8 QQuaternion: prepare isNull(), isIdentity() for constexpr'ification
...by dropping the use of qIsNull(), which, in Qt 4, distinguished
between -0.0f and +0.0f.

But mathematically, whether x, y, z are ±0 doesn't change the fact
that the result is the identity element (x, y, z should contain the
identity element for addition and w the one for multiplication), or
the null element (additive identity).

So using qIsNull() was wrong even in Qt 4. In Qt 5, qIsNull() returns
true for both ±0, so we can just as well compare to 0.0f instead,
which allows to mark these functions constexpr (qIsNull() can't be).

Do so.

cecd52b89a qstatemachine: add methods detect when a machine has processed an event
currently when adding an event it is not possible to know when processing
it has finished.
In particular if the event is ignored no method is called.
Adding virtual methods to the private implementation (binary compatibility).
These methods allow for extended automatic testing of the state machines.

(cherry picked from commit e7feb95628)

c07f5b801b QStateMachine: add internal transitions.
The behavior of "external" and "internal" transitions is identical,
except in the case of a transition whose source state is a compound
state and whose target(s) is a descendant of the source. In such a case,
an internal transition will not exit and re-enter its source state,
while an external one will.

[ChangeLog][State machine] Added support for internal transitions.

bd15b23987 QStateMachine: cache expensive calculations.
As nothing changes in the state machine when selecting transitions for
events and then calculating the exit- and entry-sets, some calculations
can be cached.

The exit set for a transition was calculated multiple times. First in
removeConflictingTransitions, where the two loops would each calculate
them multiple times. Then secondly in microstep(), which would calculate
the exit set for all transitions.

Transition selection, exit set calculation, and entry set calculation
all calculate the transition domain and effective target states for
transitions.
