Subject: [PATCH 02/21] QQmlDelegateModel: Refresh the view when a column is
 added at 0

It can happen that a model reports n>0 rows but columns=0 (See
QConcatenateTablesProxyModel). In those cases we would render glitchy
items until the elements are marked as dirty.

Subject: [PATCH 03/21] Fix TapHandler so that it actually registers a tap

This bug caused all quick examples that used the
shared\LauncherList.qml to be broken.

In QtGui, QSinglePointEvent will construct itself with a point id of 0
if there is a valid point, and with a point id of -1 if the point is
invalid (the default constructor does the latter).
However, QQuickSinglePointHandler::wantsPointerEvent() did not agree
with that, because it assumed that a point id of 0 meant
uninitialized/invalid point.
The fix is to change QQuickSinglePointHandler::wantsPointerEvent() and
QQuickHandlerPoint so that it assumes that the id -1 is now an invalid
point, (instead of 0)

Subject: [PATCH 05/21] Make sure QQuickWidget and its offscreen window's
 screens are always in sync

By default, the offscreen window is placed on the primary screen.
However, if the parent widget argument is passed to the QQuickWidget's
constructor, then QQuickWidget's and the offscreen window's screens can
be different and that can create rendering issues, e.g. blurry text if
the primary screen and QQuickWidget's screen have different scale
factors.

Subject: [PATCH 06/21] Don't convert QByteArray in `startDrag`

QMimeData::setData expects the provided data to contain the correctly
encoded QByteArray, so if the variant contains a QByteArray, then take
it as is to avoid data loss.

If the variant is not already a byte array, then we ideally would make
sure that the mime type (i.e. the key of the map) and the QVariant's
type are compatible (image/png with a QImage works; text/plain with a
QImage does not). This changes behavior and needs to be a follow-up
commit.

Subject: [PATCH 08/21] Implement accessibility for QQuickWidget
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The accessibility tree for the Qt Quick content should
be rooted at the QQuickWidget, and not at the offscreen
QQuickWindow.

For this to be the case, several things must happen:
  - QQuickWindow must not report the child interfaces
  - QQuickWidget must report the child interfaces
  - The child interfaces must report the QQuickWidget as the parent

Create accessibility interfaces for QQuickWidget and
and QQuickWigetOffscreenWindow (which now gets a proper
subclass), where the QQuickWidget interface reports
the child interfaces and the QQuickWigetOffscreenWindow
reports no children

Change the code in QAccessibleQuickItem to use the
true (visible) window, where needed.

Subject: [PATCH 09/21] Send ObjectShow event for visible components after
 initialized
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently ObjectShow event is only sent when the visible property
changes from false to true, but for items with the notification
accessible role, a screen reader like Orca needs to receive an
ObjectShow event to read the notification, so also send the event after
a component is initialized.

Subject: [PATCH 10/21] QQuickItem: avoid emitting signals during destruction

If a QQuickItem is in the QQuickItem destructor, then it is both unsafe
and unnecessary to emit property change notifications. Connected code
can no longer rely on the state of the emitting object - if it was
originally a subclass of QQuickItem, then those subclass destructors
will already have run. And the QQuickItem destructor will also have
partially run, leaving the object in an undefined state.

Add a flag that we set to true at the top of ~QQuickItem, and don't emit
visibleChildrenChanged, parentChanged, visibleChanged, and
childrenChanged for items that are partially destroyed already.

[ChangeLog][Qt Quick][QQuickItem] QQuickItem no longer emits change
notifications for the parent, children, visible, and visibleChildren
properties while it is being destroyed.

Subject: [PATCH 18/21] QQuickItem: Fix effective visibility for items without
 parent

Items are visible if they are children of a visible parent, and not
explicitly hidden. The effectiveVisible member stores the state and is
updated when conditions that impact the item visibility changes.

The old code returned true for items outside a visual hierarchy, which
broke signal emission when items were removed from a parent, e.g.
because the parent got destroyed. With this change, items removed from
a visual hierarchy will emit the visibleChanged signal.

Note: QQuickItem initializes the effectiveVisible member to true, even
if the item was created without parent item. Visual items are required
to be added to a visual hierarchy via setParentItem. For this reason,
newly created items never emit visibleChanged when they are added to
a parent.

Adjust the QQuickItem::visible test - it creates an item hierarchy
without window. Such items are never visible, so add a window and
parent the test item hierarchy to the window's content item.

This fixes the expected failures in the tests. It does introduce an
incompatibility with QGraphicsView and QGraphicsItem, which continue
to return true from QGraphicsItem::isVisible for items that are not
in an item hierarchy.

[ChangeLog][Qt Quick][QQuickItem] The visible property of Items without
a parent now always returns false, and the visibleChanged signal gets
emitted when the parent item of a visible item becomes null.
