The match FcPattern should be managed by QFontDatabase instead of
QFontEngineX11FT since the latter only used it once.

We should do FcConfigSubstitute(0, pattern, FcMatchFont) on a
FcPattern for query because the family list in it will contain
almost all the families after FcConfigSubstitute(0, pattern,
FcMatchPattern), then the test in <match target="font"> will
almost always succeed. In general, FcMatchFont substitute
should only be done on the FcPattern that we got after
FcFontMatch() or FcFontRenderPrepare().
Based on the suggestion of fontconfig author Behdad Esfahbod,
this patch reorganized the tryPatternLoad logic so that it only
does the QFontEngine creation part, FcPattern *match is retrieved
outside of that function. In this way, the match pattern we got
can be either from FcFontMatch() or after FcFontRenderPrepare()
on one of the fonts we got from qt_fontSetForPattern(). Then we
don't need to duplicate the pattern and add all criterias back
with qt_addPatternProps(). It not only simplified the code a lot
but also fix the way we apply FcMatchFont substitution. This
substitution will either be done by FcFontMatch() or
FcFontRenderPrepare, both implicitly.

Moved the logic to set pixel size into the font engines to avoid
making the platform plugin interface too complex, and added a function
in QPA to make an isolated font engine based on font data. Currently
none of the QPA back-ends supports it, but it compiles and spits out
a warning if you try to create a QRawFont from data there. This isn't
used in QtQuick2 anyway.

For Qt apps running in GNOME, we use the GTK+ settings by

QFontEngineFT are used in raster/OpenGL paint engine and QGLWidget,
also in Symbian, etc. We want to make sure it works well in raster
and QGLWidget first. Regardless subpixel antialiasing (LCD filtering)
is enabled or not (though it does look better when subpixel
antialiasing is on). We also need to support transformations.
The tricky part here is that, under X11, we have a different code
path for QFontEngineFT and other font engines in raster engine,
which uses QFontEngineFT's own glyph cache system. While in other
platforms (Windows and Mac) and QGLWidget, we will use the generic
QTextureGlyphCache.
The generic QTextureGlyphCache already has support for subpixel
positions, this solution is ported to QFontEngineFT for its
QGlyphSet: the key for QGlyphSet hash table has been extended from
glyph_t to <glyph_t, QFixed subPixelPosition> pair.
The real work to enable subpixel positioning with FreeType is in
fact really simple, we just set the horizontal translation to the
subpixel position * 64 (FreeType uses a coordinate system of 1/64
of a pixel resolution internally) immediately before loading the
glyph. A slight tweek to bitmap width is applied when we are
getting the bitmap ourselves instead of using FT_Render_Glyph to
accommodate the subpixel translation, which will only be used in
non-LCD filtering cases (grayscale antialiasing).
From what we have observed, FreeType can generate different bitmaps
for at least 12 different subpixel positions (each with a slight
difference). To limit the memory consumption, we restrict the
number of subpixel positions to be 4 (hardcoded), which should be
good enough for most low resolution displays.
Subpixel positioning (and fractional glyph advances) will only be
enabled when the hintingPreference for the font being used is
PreferNoHinting or PreferVerticalHinting. We will use fontconfig
hintstyle setting by default when no hintingPreference is set for
the font.

When FontConfig was enabled, bitmap fonts would often get a different
pixel size than the one we requested. Usually the size would only be
a pixel off, but this was especially visible when printing in highres
with bitmap fonts, because in those cases we would request a pixel size
which was computed based on the printer's high dpi.
The result was that all printed text with bitmap fonts would be really
really tiny. The fix falls back to using the XLFD font engine when
using bitmap fonts (when the returned pixel size is different from the
requested), because this engine scales the fonts for us. This will
cause bitmap fonts to be rendered without antialiasing.
