This define is also used by the OpenVG module, and therefore needs
to be defined everywhere.

qfontengine_ft.cpp uses the function FT_GlyphSlot_Embolden but
ftsynth.c (where the function is implmented) isn't compiled in when
QT_CONFIG contains freetype.

QStaticText was previously made private API to support inclusion in
Qt 4.6.x. This change turns it back into public API for Qt 4.7.0.

Turns QStaticText into private API in preparation for Qt 4.6.x. The
related functions in QPainter are marked as internal in the docs. There
are already internal functions in QPainter, so this seemed like a
reasonable solution. Since the functions require QStaticText they will
not be accessible to anyone who does not include private API.

Much of the time in drawText() is used on text layouting, which is
wasted time when the text is not updated every frame. QStaticText is
meant to cache the relevant parts of this work. It currently uses
a copy-paste of the layout code in QPainter::drawText() and 99% of the
time in QPainter::drawStaticText() is spent in drawTextItem(). We can
use QTextLayout here instead without losing much.

QTextEdit (via QTextLayout) and QPlainTextEdit in Qt used to ignore
any font leading but added one extra pixel in QFontMetrics. With many
freetype fonts, this resulted in a "spacy" text layout.
The necessary fixes on X11 and Windows were to take (positive) leading
into account, to make the font database convert point sizes to pixel
sizes without rounding to plain integer values, and to subtract the
extra pixel from QFontMetrics from the font engines' descent value.
The change also fixes several places in styles and widgets, where
QFontMetrics::lineSpacing() was wrongly used instead of
QFontMetrics::height().
Ideally we should also handle negative leading, which would require
additional and bigger code changes in QTextLayout and QPlainTextEdit.
In addition, all other editors we have tested seem to ignore leading on
X11. If we choose to believe the values provided by freetype, our text
layout would be one pixel smaller than everybody else's.
On the Mac, this change does nothing. There our layout is still too spacy,
and for smaller fonts quite ugly compared to native Mac applications.
Done with mae.

On the Mac, it means "-framework ApplicationServices -framework Carbon
-framework AppKit" are no longer part of the default LIBS in Qt
applications. This required a lot of fixes where we used Mac-specific
code in Qt.
On X11, it was very straightforward, because we apparently use very
little of X11 outside QtGui.
I haven't changed the Windows-specific LIBS paths, because I don't
know how Windows behaves. Windows has DLLs, but it links to static
"import" libraries. So is it static linking or dynamic linking?
