Similarly to QS60PixmapData, that is used on raster, QVGPixmapData
is also backed by a CFbsBitmap from now on (at least when it makes
sense to do so). This allows copy-less bitmap handle duplication in
from- and toSymbianCFbsBitmap() in case of certain image formats,
reduces local heap usage and improves performance with the s60 style
due to a reduced number of pixel data copies.

If QPixmap::fromImage() was called with a QImage that has an alpha
channel and with the 'Qt::NoOpaqueDetection' image conversion flag set,
then we would always create an opaque (RGB32) pixmap. This is
incorrect.
The fix is to check if the source QImage has an alpha channel and if
so, use sourceFormat(), otherwise use RGB32.

The QPainter::fillRect() functions are optimizations to avoid state
changes in the paint engines. Since these functions should be
completely independant of state, ideally they should only call
functions that are also stateless.
QVGPaintEngine::fillRect() has two different code paths for this.
The vgClearRect() path of this function is stateless however in the
case of non-opaque or complex fills, this code path cannot be used and
instead we use the normal path fill function which is not entirely
stateless because ensureTransform() will apply the aliased coordinate
transform if the current state includes a stroked pen.
To avoid this happening for a pure fill (no stroke) we temporary set
the pen state to be Qt::NoPen such that the state used by
ensureTransform() is correct.

Stroking a path can sometimes result in inconsistent rendering
especially when combined with a clip. For example, if the logical edge
of a clip rect coincides with the logical edge of a path then it can
happen that the edge is not painted correctly because the stroke lies
outside the bounds of the clip rect. To workaround this problem, we add
the 'aliasedCoordinateDelta' such that the rounding will err on the
side of caution. This improves the correctness when using the raster
engine as a reference.

The reclaimSpace() function of the VG image pool was crashing when
attempting to free up space for a large image. It was calling
moveToHeadOfLRU() which adds the image to the pool. If the pixmap is
large enough so that it pushes all the others out, then it will be the
only pixmap left in the pool when this function returns. This is
problematic because this pixmap is not permanent so it could be
deleted. If that happens, then subsequent calls to this function will
crash because the LRU pixmap has been deleted.
The fix is to check if the pixmap was in the pool to begin with and
if not, then be sure to remove it before returning from this function.

Commit b0bbabe728fedb8531fc2837403856bd5ed44e1b fixed text blurriness
in the OpenVG paint engine by forcing the coordinates of the text
items to integer coordinates (for unrotated, unscaled text).
That was not yet enough. In addition to the coordinates, also the
d->pathTransform in QVGPaintEngine can have a non-integer translation.
This patch makes sure that the text item coordinate combined with the
translation result in final integer coordinates.
Since it is not possible to set an absolute translation of a
QTransform (only relative is possible), first dx() is added to p.x(),
then after rounding, it is again substracted. Sam for y, but with
opposite prefix, since the y-axis in Qt and in transformation
matrices are in opposite directions.
The ceil stunt (which I cerated by trial and error) was replaced
by floor(x + aliasedCoordinateDelta), which *exactly* what other
paint engines do.

Proxy widgets use the shared painter functionality and this implies
that the paint engine's begin function does not get called for each new
widget that gets painted. This causes a problem because the system clip
gets modified by QPainter, but the paint engine does not realize that
this happened and fails to use the new clip. The result is that you can
end up painting outside the intended clip area.
The fix is to reimplement the virtual systemStateChanged() function in
QVGPaintEnginePrivate and make it call updateScissor() to re-evaluate
the clipping flags and update the current clip accordingly.
A similar fix was done to the OpenGL paint engine way back in 307c2954.

The convertToPainterPath() function assumes that the QVectorPath
contains at least one path element when creating the QPainterPath. This
is not necessarily the case here though because if QVG_SCISSOR_CLIP is
defined and setClipPath() is called with an empty QPainterPath, this is
then converted to an empty QVectorPath in QPaintEngineEx::clip() which
then calls QVGPaintEngine::clip(). This function then goes on to
convert the QVectorPath back into a QPainterPath using the
aforementioned function which crashes when attempting to access the
first element of the path.
In case you are wondering why this seemingly redundant conversion
happens at all, it happens because when QVG_SCISSOR_CLIP is defined, we
attempt to convert the path to a series of rects for scissor clipping
and this conversion function operates on QPainterPath instead of
QVectorPath which is what this clip() function was designed to deal
with.
The fix is to skip over the path conversion for empty paths and go
directly to an empty QRegion.

Qt's graphics system uses qreal as measurement unit.
The established paint engines (such as "raster") implicitly
round textitem coordinates for technical reasons, e.g. for
optimized blitting.
Some Qt based Ui libraries (such as QWidgets) can in some
cases cause textitems to be drawn on non-integer coordinates.
In particular, this happens when centering text.
Since these libraries have been developed against the
established paint engines with implicit rounding, these
non-integer coordinates were never an issue.
The new OpenVG paintengine took these coordinates seriously
without rounding them. On some OpenVG implementations (e.g.
that of some Symbian phones), this led to blurry text
rendering.
This patch adds coordinate rounding for unscaled, unrotated
textitems to the OpenVG paintengine. So that it does the
same as the raster paint engine.

The OpenVG paint engine traditionally takes glyph images from the
alphaMapForGlyph() function which returns the glyph image in the
upright projection. When it constructs a VGImage from this image, it
passes a positive data stride which will read the top scanline of the
source image into the bottom scanline of the VGImage due to the VG
coordinate system. It then uses the path transform where the 'sy' value
of the matrix is set to -1 and this re-inverts everything when drawing.
With the Symbian based glyph cache, the VGImage is constructed from a
RSgImage which is a hardware resource and compensates for the
coordinate system used by VG and GL at the time it is created. In
the case of the hardware glyph cache, the glyph image is read into the
RSgImage using a negative data stride so it does not need to be
inverted when drawn. To allow for this, introduce a flag which
indicates that the 'sy' entry of the matrix should be flipped such that
the glyph is drawn normally.
Also in this patch is a change to the glyph origin which now uses the
bottom of the glyph metric bounding rect instead of the top due to
orientation of the glyph inside the VGImage.

This introduces a specialized OpenVG font cache for the Symbian
