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.

Previously subpixel positioning was only used when subpixel rendering
is enabled (glyphType == Raster_RGBMask), however, it does not
necessarily require that and for Mac OS X it will keep using
subpixel positioning even when LCD font smoothing (subpixel rendering)
is turned off. To maintain consistency when switching to raster,
we should support subpixel positioning in this case.

It is only used by the fontengines. This is one of the steps to make it
easier to make fontengines build outside of QtGui.

While drawText() will use the path fallback for large fonts, and never
hit this problem, QStaticText will draw the large fonts into the glyph
cache. This broke when the freetype (or any other font engine) falls
back to the generic implementation of alphaMapForGlyph() which uses
path drawing. The problem was that alphaMapForGlyph() is not supposed
to contain the bearing of the glyph, only the actual pixels. Since
QFontEngine did not honor this contract, we would sample the wrong
area in the glyph cache to get the glyph image.

For the raster engine to provide the same quality of text rendering
as the native engine on Mac Cocoa, we need to support rendering to
different sub pixel positions for each glyph. The number of
subpixel positions is arbitrary and has to be detected, but it's
usually three or four.
Each position will give slightly different coverages inside the
pixel and thus different rasterizations. Other font engines which
support sub pixel positioning of glyphs can provide the same
functionality by implementing supportsSubPixelPositions() to return
true, and then adding the subPixelPosition argument to the x
coordinate used in alphaRGBMapForGlyph().

QPlatformFontDatabase added. QPlatformIntegration now has a new virtual
function: QPlatformDatabase::fontDatabase() const. Most unix platform
plugins wants to follow the pattern implemented in directfb, linuxfb,
vnc etc. In the pro file do:
include(../fontdatabases/genericunix/genericunix.pri)
In the QPlatformIntegration class do:
and instansiate a QGenericFontDatabase in the constructor and return
it in the getter function.

For fonts that have an AppleRoman name table, *isSymbolFont failed to
return correct value even if they have a symbol table. This patch
corrected this behavior by using symbolTable variable to detect that
instead of checking if score == Symbol.
Also prefer symbol table over AppleRoman table to make generic CMap
decoding consistent with QFontEngineFT (which will use the symbol table
whenever its available).

Commit 07880542ecc479807c23c5646d263135240822ff introduced regression to
QFontMetrics::boundingRect and QTextEngine::boundingBox on FT, XLFD and
QPF font engine. Because on these platforms, rightBearing of the last
glyphs is already removed from the width returned in glyph_metrics_t.
Subtracting that rightBearing twice will cause the resulting boundingBox
smaller than expected.
This patch fix this by removing last right bearing accounting code from
generic QTextEngine::boundingBox, instead, we put it into font engines
that need them: QFontEngineWin, QCoreTextFontEngine, QFontEngineMac,
QFontEngineS60 and QFontEngineQWS. So that the resulting width should be
correct on all platforms without introducing any performance penalties.

Lighthouse is a lighter, nimbler version of Qt/Embedded, which does not
contain a window system. Instead, it uses graphics system plugins to
provide the necessary functionality or interface with existing window
systems.
The first version was written by Rhys.

QFontEngine will delete its glyph cache (and if it's a GL engine, its
texture) when the font engine dies. The font engine can die when the
QFontCache decides to clean it up, e.g. based on the trigger of a timer.
To make it possible to use the glyph cache elsewhere, without
interference by the font cache, it has been made explicitly shared.

Introduce an API to access glyph indexes in a font directly.
A bug was discovered during this work, where different hinting flags
in loadGlyph() and loadGlyphMetrics() would make the metrics in
the two functions different, thus causing drawCachedGlyphs()
(which uses loadGlyphMetrics() indirectly) to use different metrics
than the standard drawTextItem() code path (which uses loadGlyph()).
The bug was visible in the tst_QGlyphs::drawExistingGlyphs() test.

the original commit because of a test failure on qws. This recommit adds
a test for whether the metrics from QFontEngine::boundingBox() are valid,
which is required for the bearings to be calculated. This test was also
in the original logic.

The line separator code point has no glyph in any font, something we
would detect by running through a complete font merging loop and trying
all fonts in the system on X11. This would cause the memory consumption
to sky rocket the first time you added text with line breaks to an
application, and it was an unnecessary performance hit. Now we special
case the line separator and do no attempt to search for it in the
fonts.

Some symbol fonts will contain a unicode cmap table in addition to the
microsoft symbol cmap table that maps the symbol range (private range
0xf000 - 0xf100) into the correct glyphs. This is essentially a broken
unicode table, and we should not prefer it if these conditions are true.
In the strict cases where these conditions apply, we fall back to the
symbol table instead.
