Rounding the coordinate pre-transformation leads to pretty big
positioning errors when the painter has a large scale, and small source
coordinates are used.

(Backport from master)
Currently we only pass the num_glyphs for the run to
HB_ShapeItem, but it can be less then the string length
for this run because of Unicode surrogates. Thus, we need
to pass at least the length of that run as num_glyphs to
HB (given that we have enough space allocated because for
the entire string), if that's still not enough, we will
do ensureSpace again according to the num_glyphs returned
by HB and move remaining glyphs backwards.

If there is a graphicsview with input widget focused and splitview is
open, and we rotate the device from Portrait to Landscape
(or vice versa), the input widget is no longer visible in the
splitview rect. This only happens if there are scrollbars visible
in the view.
Reason is that the input widget is tried to ensure visibility for
before window surface is valid. In these cases, make the input widget
visibility re-location happen after window server indicates that the
view is now visible.

Previously, the following rules applies to the creation and blitting of
the Symbian raster backing store:
1. Creation of backing store with an alpha channel:
Backing store has an alpha channel only if !QWidget::isOpaque.
2. Pre-filling of backing store prior to paint loop:
Backing store is filled with transparent pixels if
!QWidget::isOpaque.
3. Blitting of backing store:
CGraphicsContext::EDrawModeWriteAlpha is used (meaning that backing
store alpha values are propagated into the frame buffer), if
QWidget::isOpaque.
In order for the direct camera viewfinder to be visible on DSA devices,
alpha=0 must be written into the framebuffer in the region where the
viewfinder will be displayed. This requires a backing store with an alpha
channel (1), use of CGraphicsContext::EDrawModeWriteAlpha (3), but not
pre-filling of the entire backing store (2).
This patch adds a new enum value, QWExtra::BlitWriteAlpha, which can be
used by camera backends to achieve the desired behaviour.

When set for an item, QGraphicsScene will skip focus handling for this item and
everything underneath it (including focus-out). Allows users to reimplement
custom focus handling.
Use case: touch devices that implement panning. Here, focus-in has to happen
only if no panning was triggered. Analogous, no focus-out should happen when
panning was detected.
Fixes the alternative proposal ("black holes for focus changes") of
QTBUG-16343: QGraphicsView doesn't support focus change on mouse release.
The previous test was only testing one scenario, which didn't give a good idea
whether the flag was actually working as intended.

Background texture is not created until it is actually painted.
This allows skipping the whole background texture creation, if app
overwrites the QPalette::Window with its own data (image or color).
When widget is drawn and style notices that the widget is still using a
placeholder (1*1 red QPixmap) texture, it creates the real texture and
uses that for drawing.
Note that accessing QPalette::Window will give the placeholder pixmap.
Which is then again replaced with the real texture, if it is drawn
through the qt_s60_fill_background().

Fix for QTBUG-16816 cause theme background to display incorrectly
after a layout switch is done. Theme background is shown "tiled"
instead of being whole screen size.
This is because the setBackgroundTexture() call was removed to "save"
QPixmap creation. Unfortunately, it really skips the background
texture creation, but does not re-create a new one for the new layout,
so portrait background is used again. This leads to tiling the image.
Let's just return the call to the setBackgroundTexture()
(this will eventually anyway be "optimized" with fix for QTBUG-14910).
