- Replace Nokia contact email address with Qt Project website.
- Remove "All rights reserved" line from license headers.
As in the past, to avoid rewriting various autotests that contain
line-number information, an extra blank line has been inserted at the
end of the license text to ensure that this commit does not change the
total number of lines in the license header.

The Symbian Font Table API is a feature from (the former)
Symbian^4 which will be backported into Symbian^3 in a
random minor OS version. In order to keep Qt source and binary
compatible between these minor versions, we cannot decide at
compile time whether or not to use the new Font Table API.
This patch changes many "#ifdef Q_SYMBIAN_HAS_FONTTABLE_API"
into "if (symbianFontTableApiAvailable())". The Font Table
feature is detected at runtime. Currently, CFeatureDiscovery
is not used, because at the time of writing, that feature flag
test would give false positives or false negatives. Instead,
CFont::ExtendedFunction() is called with KFontGetFontTable to
see if the return value is KErrNone, which indicates that the
feature is available. The avalibility information gets cached,
so the hack happens only once per application run.
The font table Api feature comes with helper classes such as
"RFontTable" and "TGetFontTableParam". But we cannot use those,
because we want to stay source and binary compatible across the
Symbian(^3) versions without the Font table API and those with.
So, in Qt, RFontTable is simply not used and TGetFontTableParam
is replicated as "QSymbianTGetFontTableParam". Same for
KFontGetFontTable, KFontReleaseFontTable and later also
FfFontTable.
This patch has been looked at by colleagues, who verified the
overall #ifdef to if() conversion, but did not feel entitled to
give their official Reviewed-By for an obscure topic like Qt
font support on Symbian. (It sucks to be the only creature in
this universe who -kind of- knows how Qt text handling and
Symbian text handling interact)

Some glyph position tweaks during the shaping phase require
the "Units per Em" information for the font. QFontEngineS60
did not reimplement emSquareSize(), therefore, some combined
glyphs were rendered incorrectly (see QTBUG-10725)
This patch implements QFontEngineS60::emSquareSize()
Since Symbian does not provide the "Units per Em" via public
Api, we have to pick that out of the 'head' font table.
The value is cached per font.

This introduces a specialized OpenVG font cache for the Symbian
platform. By using RGlyphDataIterator we can create a VGImage to store
inside a VGFont without having to upload our own glyph image. This
works by utilizing RSgImage which can be used to share handles to
graphics memory across processes thus allowing glyph images to be
shared by multiple processes and reducing graphics memory usage.

Factor out the Symbian specific bits of QVGPixmapData into a separate
file and introduce our subclassed implementation of the VG font cache.
Also make our font cache a friend of the S60 font engine because the
cache needs to access the CFont member to create the glyph image.

Up until Symbian^4, the Symbian font Api does not provide access to the
vector data of glyphs. In order to make QPainterPath::addText() and
transformed text rendering work, Qt falls back to a workaound: Tracing
the bitmap of a rasterized glyph. That is neither performant nor is the
result of good quality.
Symbian^4 will add Api that returns glyph outlines encoded as SVG paths.
The code in this commit essentially parses the SVG path and returns a
QPainterPath. The parsing part took some ideas from QSvg, and is
implemented in a very reduced way.

Qt requires raw access to the font tables of used fonts, for a
variety of reasons.
Until Symbian^4, it is/was not possible to access the font tables of
the fonts which are stored in Symbians Font and Bitmap Server.
That's why Qt for Symbian's FontDataBase created an own TFontStore
where it loaded in all installed fonts. While accessing the font
tables via the own TFontStore it still uses the rasterization and
metrics from the FBS, which has public Api for those things.
However, loading all fonts in the own TFontStore for each Qt Gui
process slows down the program startup. Symbian's future font table
setter Api is very welcome and this implemets it's usage.
This patch lets Qt use the new font API on Symbain^4. The font
tables are retrieved via RFontTable.

That reduces the delta between 4.6/4.7 and a patch that I am pre-

That function was not yet implementing. Its absense caused some
Harfbuzz based shaping not to happen.

Since QFontEngineS60 is private implementation and generally not
exported, no symbols need to be added to the .def files for this patch.

Text rendering in Qt for Symbian looks very bad on a scaled QPainter.
Instead of simply using a Symbian font with the right size it followed
the code path that is usually used for "tricky transformation":
Use the glyph outlines and rasterize them in Qt as QPainterPath.
That's slow and especially ugly on Symbian since we do not (yet)
get the glyph outlines from Symbian.
This patch adds QFontEngineS60::setFontScale() so that QFontEngineS60
has one additional native font handle with the scaled size. The raster
paint engine will call that function in case that the painter is scaled.
Since we already have QFontEngineS60 specific code in the raster paint
engine, this patch did not have to add #ifdefs.
