Long live QRawFont!
The QGlyphs API was initially attempted with a bastardization of QFont which was meant to encapsulate a single, physical font instance (a QFontEngine) where a set of glyph indexes would make sense. This is not how QFont was intended to be used, and it caused several issues. At the same time, the requirement for loading a font from ttf/otf data and be able to access it and use it without polluting the rest of the process with the font arose. To support these two APIs we introduce QRawFont, which is an abstraction on top of a single physical font. Done-with: Jiang Jiang

+ \class QRawFont
+ \brief The QRawFont class provides access to a single physical instance of a font.
+ \since 4.8
+
+ \ingroup text
+ \mainclass
+
+ \note QRawFont is a low level class. For most purposes QFont is a more appropriate class.
+
+ Most commonly, when presenting text in a user interface, the exact fonts used
+ to render the characters is to some extent unknown. This can be the case for several
+ reasons: For instance, the actual, physical fonts present on the target system could be
+ unexpected to the developers, or the text could contain user selected styles, sizes or
+ writing systems that are not supported by font chosen in the code.
+
+ Therefore, Qt's QFont class really represents a query for fonts. When text is interpreted,
+ Qt will do its best to match the text to the query, but depending on the support, different
+ fonts can be used behind the scenes.
+
+ For most use cases, this is both expected and necessary, as it minimizes the possibility of
+ text in the user interface being undisplayable. In some cases, however, more direct control
+ over the process might be useful. It is for these use cases the QRawFont class exists.
+
+ A QRawFont object represents a single, physical instance of a given font in a given pixel size.
+ I.e. in the typical case it represents a set of TrueType or OpenType font tables and uses a
+ user specified pixel size to convert metrics into logical pixel units. In can be used in
+ combination with the QGlyphs class to draw specific glyph indexes at specific positions, and
+ also have accessors to some relevant data in the physical font.
+
+ QRawFont only provides support for the main font technologies: GDI and DirectWrite on Windows
+ platforms, FreeType on Symbian and Linux platforms and CoreText on Mac OS X. For other
+ font back-ends, the APIs will be disabled.
+
+ QRawFont can be constructed in a number of ways:
+ \list
+ \o \l It can be constructed by calling QTextLayout::glyphs() or QTextFragment::glyphs(). The
+ returned QGlyphs objects will contain QRawFont objects which represent the actual fonts
+ used to render each portion of the text.
+ \o \l It can be constructed by passing a QFont object to QRawFont::fromFont(). The function
+ will return a QRawFont object representing the font that will be selected as response to
+ the QFont query and the selected writing system.
+ \o \l It can be constructed by passing a file name or QByteArray directly to the QRawFont
+ constructor, or by calling loadFromFile() or loadFromData(). In this case, the
+ font will not be registered in QFontDatabase, and it will not be available as part of
+ regular font selection.
+ \endlist
+
+ QRawFont is considered local to the thread in which it is constructed (either using a
+ constructor, or by calling loadFromData() or loadFromFile()). The QRawFont cannot be moved to a
+ different thread, but will have to be recreated in the thread in question.
+
+ \note For the requirement of caching glyph indexes and font selections for static text to avoid
+ reshaping and relayouting in the inner loop of an application, a better choice is the QStaticText
+ class, since it optimizes the memory cost of the cache and also provides the possibility of paint
+ engine specific caches for an additional speed-up.

+ alphaMapForGlyph().

+ The returned image contains the alpha values of each pixel based on the coverage of
