This documentation is misleading, as the internal representation of a
QPixmap is not guaranteed to be RGB32 or ARGB32_Premultiplied, and
whether it's stored client side or server side also depends on the
graphicssystem.

QPixmaps might be unintentionally created through QVariant streaming for
example, so to prevent breaking existing applications we should just use
a warning instead, when creating a QPixmap in a non-GUI application.

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.

The behavior now matches the raster (s60) pixmap: A bitmap is created
immediately when constructing from a QImage. This is needed to reduce
the heap usage of applications (by getting rid of the QImage as early
as possible).

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.

From fixing qwidget autotest, it seems to be the case that filling
a pixmap with a solid color on mac changes the hasAlpha status. This
is different from X11 (and raster engine). That is, the following
code will produce different result:
QPixmap pixmap(100, 100);
pixmap.setAlphaChannel(QPixmap(100, 100));
qDebug() << "Has alpha after setting channel?" << pixmap.hasAlpha();
pixmap.fill(Qt::red);
qDebug() << "Has alpha after fill?" << pixmap.hasAlpha();
So, this patch remove the possibility of converting an already alpha
supporting pixmap to non-alpha upon fill. NB: somewhat related, the
following code works the same on both x11, raster and mac (prints
'false'), but still seems wrong:
QPixmap pixmap2(pixmap);
qDebug() << "pixmap2 has alpha initially?" << pixmap2.hasAlpha();

depending on platform, qBinaryFind might be up to 3 times faster than bsearch
or a bit bit slower at the worst case; so why don't simply use qBinaryFind instead of bsearch and be an optimist? ;)
also we know that all color names are in the lower case already and thus
we can avoid lowercasing of them again and again, and again;
the name to find needs to be lowercased separately instead.
