When the creation of the EGL window surface failed, the paint engine
was not destroyed in the openvg module's window surface implementation.
This led to accessing an obsolete engine instance later on in
QSymbianControl::Draw, leading to a crash. Now a new, proper engine
will be created, naturally the painting will still fail, but the
application will not crash.

When drawing such pixmaps (used by both the openvg and opengl graphics
systems) onto another pixmap or to a QImage, the performance was
sub-optimal due to missing and accidentally disabled support
specific to QVolatileImage. This is now fixed and drawing pixmaps into
a QImage is also made optimal by using the QS60PaintEngine for
QImage too. This will cause a 5-7x (or even up to 12x on certain
hardware and platform) increase in offscreen pixmap drawing
performance.

Remove ugly TemporarilyCachedBindOption and use QGLTexture
objects as texture pool entries instead of QGLPixmapData.
Make texture pooling totally Symbian specific, remove
VG like texture pooling code and use common texture binding
path which is used on other platforms also on Symbian.
QGLPixmapData should be only used to bind SgImage based
textures (will be implemented by another commit).

Flushing native child widgets in VG and GL window
surfaces caused performance downgrade because unnecessary
swapBuffers calls. On Symbian we must not support flushing
native child widgets in VG and GL window surfaces because
it causes GPU memory overhead and performance issues. Symbian
graphics architecture allows us to render native child widgets
to TLW EGL surface correctly in most of the cases.

When a painter is open on a pixmap's underlying QVolatileImage, it is
better to upload the VGImage content every time the pixmap is drawn
on the screen, in order to enable showing animations that are created
by continously rendering into the same pixmap and keeping the same
painter open.

The OpenVG engine correctly uses vgClear() to fill the surface with
transparent pixels whenever the window has the WA_TranslucentBackground
attribute enabled. However both scissoring and masking affects
the operation of vgClear(). Drawing artifacts were previously
visible due this, simply because scissoring was left enabled by
the VG paint engine, and the filling with transparent pixels
happens in the window surface's beginPaint() that is called
between the paint engine's end() (for the previous paint) and
begin() (for the next paint).

Unlike OpenGL, the EGL_SWAP_BEHAVIOR_PRESERVED_BIT was not set for

The vgWritePixel-based "fallback" in drawImage can only be used when
the transformation is simple and no opacity is set. The tiled drawing
introduced here will serve as an additional fallback for the more
complex cases and will allow drawing large (12 Mpix or more) pixmaps
and images with transformation and semi-transparency even when the
complete image data would not fit into the GPU memory.

Inverting the pixels for bitmaps of mode EGray2 is done in-place,
which is wrong if the bitmap handle was duplicated. Instead, we
need to make a copy. This also means that we cannot treat EGray2
a conversion-less format in openvg, but such images are likely
to be used as masks only, so optimizing just for mere drawing
in case of this format is not really necessary.

From now on the image data coming from CFbsBitmap will not be forced
to RGB32 or ARGB32_Premultiplied in openvg. This allows copy-less
creation and drawing of pixmaps not just from bitmaps with display mode
EColor16MAP and EColor16MU, but also a few other modes, like EColor64K.
Painting into such pixmaps or drawing them via the raster engine is
potentially slower in such cases, which is now reflected in the
fromSymbianCFbsBitmap documentation.
Note that this patch has no effect on extended bitmaps (e.g. skin
graphics), those must always be rasterized first regardless of the
display mode.

QNativeImageHandleProvider is a thin interface consisting of get()
and release() functions. Pixmaps constructed with such a provider
will call these functions to acquire and release a native handle,
e.g. a CFbsBitmap or RSgImage pointer in case of Symbian. The behavior
is largely similar to constructing pixmaps via fromSymbianCFbsBitmap
or fromSymbianRSgImage, with the exception of pixmap hibernation:
release() (and subsequently get()) is guaranteed to be called also
in case of hibernation, allowing more fine-grained tracking of
the usage and lifetime of image data.

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.
