The cache wasn't invalidated for widgets with a graphics effect inside a
scrolling QScrollArea, so for now we disable caching for widget source
pixmaps. Also, we can't clip the source pixmap to device coordinates
since there's no knowledge of which areas of the source pixmap the
effect uses to compute the visible pixels. See change fd30cc9fabe6fc023
for the graphics item effect backend fix.

The source pixmap shouldn't include the window background, as the
graphics effect might then overwrite other widgets.

The problem appeared with KLineEdit and its proxy style.
When setting a stylesheet, we create a QStyleSheetStyle in 9# and set it
to the widget, which receive a changeEvent, that will set again the style
so 3# will create a new QStyleSheetStyle with the new proxy. and set it.
in 2# we will dereference the 'old' QStyleSheetStyle (the one created in #9)
that will destroy it.
Then, later in #7, we will still access that style ('newStyle') and we crash
0# QStyleSheetStyle::~QStyleSheetStyle()
1# QStyleSheetStyle::deref()
2# QWidgetPrivate::setStyle_helper(QStyle*, bool, bool)
3# QWidget::setStyle(QStyle*) (qwidget.cpp:2523)
4# ChangeEventWidget::changeEvent(QEvent*)
[...]
6# QCoreApplication::sendEvent(QObject*, QEvent*)
7# QWidgetPrivate::setStyle_helper(QStyle*, bool, bool)
9# QWidget::setStyleSheet(QString const&) (qwidget.cpp:2470)
The solution is to change the order, and do not use 'newstyle' after
we sent the event.
The origStyle is now protected wy a QWeakPointer, but this is
just for safety reason and not related to the crash.

The driver in the N900 doesn't support glCopyTexSubImage
or glReadPixels for FBO's that have a GL_ALPHA or POT
color attachment. The ifdef'ed code in resize() was
a previous attempt to make this work which didn't.
We could have changed the texture to be GL_RGBA and changed
the texture size to be NPOT, but that would have wasted
precious GPU memory and would have been slower, so we
waste a bit of system memory instead, by having a QImage
copy along with the texture.

Change 02532ec80375c686503c4250c6ad6bb211515ec8 removed the early-exit
for 0 byte reads, causing us to hit code that assumed the buffer was
empty since nothing was read. It would thus read more into the end of
the buffer, causing the buffer to grow bigger than QIODEVICE_BUFFERSIZE.
Next, if the actual number of bytes we wanted to read was bigger than
the original buffer size we'd read the same data twice.

A mapping was being created after QStandardItem::dataChanged() signal,
even though one of the item's ancestors was being filtered out by the

If the child rect is bigger than the parent rect and parent has the
ItemClipsChildrenToShape flag set, then by updating the child, the whole
child rect is marked as dirty, resulting in a much larger update area
than required. This has a major impact on performance in Orbit/HB,
where e.g. item-views typically consist of a container item that clips
its children/items to shape. See attached video in QTBUG-9024.

Normally Qt uses scrollbuttons together at right (for LeftToRight UI)
side of the horizontal QTabBar; for vertical tab bar, scrollbuttons are
displayed below/above the widget.
Using QTabBar's scroll buttons with touch device that has capacitive
screen, is somewhat hard as the touch area for either of the scroll
buttons is somewhat smallish. So user is experiencing frequent wrong
taps. Making the touch area larger, would make the tabbar tab shape
area smaller, so it isn't a very good solution.
Therefore, when QS60Style is in use, QTabWidget draws the scrollbuttons
on either side of the QTabBar.

Found during investigation of QTBUG-8820, and clearly visible in
examples/graphicsview/diagramscene when slowly moving an item out of the
viewport (left and top edge). Caused by two problems:
1) Using QRectF::toRect() instead of QRectF::toAlignedRect().
2) Didn't adjust the item's bounding rect properly in drawSubtree().
QRectF::toRect() is completely useless since all the coordinates are rounded
to the nearest integer. E.g. QRectF(-0.4, -0.4, 10.4, 10.4).toRect()
-> QRect(0, 0, 10, 10), whereas toAlignedRect() returns QRect(-1, -1, 11, 11).
Then when we have a proper aligned rect, we have to adjust it by 2
pixels in all directions (or 1 pixel in case of
QGraphicsView::DontAdjustForAntialiasing). At first glance this
adjustment seems too much, since one would assume adjusing the QRectF by
0.5 before using toAlignedRect() would be sufficient. That's sufficient
in an untransformed world with pens using BevelJoin. However, the story
is completely different as soon as the world is transformed or the pens
use a different join. It's basically complicated (in some cases
impossible) to calculate a pixel perfect aligned QRect, so instead we
adjust by the amount of pixels required in the worst case.
This commit also includes some optimizations for QRegion updates (since
I anyways had to change the code). There's no point in using QRegion
granularity if the viewport update mode is either FullViewportUpdate or
BoundingRectViewportUpdate.
Auto tests adjusted and new ones included.
