If an entire font family is condensed or stretched and we match by
family name, the default stretch factor of 100 will make the font
engine try to synthesize it back to medium stretched font.
The existing code is already made to deal with a stretch of 0 that is
no longer used. This patch reintroduces 0 stretch to indicate no
specific stretch has been requested. Specifically setting stretch to
100 on a QFont will introduce the old behavior.
[ChangeLog][QtGui][QFont] The default value of QFont::stretch() is
now 0 to indicate any default stretch is acceptable.

Font style names are quite irregular and the simplistic matching
implemented in QFontDatabase::styleString(const QFont &) is unable to
properly resolve the style name when font is recreated from a string.
This causes the fonts before and after serialization to be considered
different, even though they are not. The from/toString methods were
made to write and respect the exact font style.
[ChangeLog][QtGui][Important Behavior Changes] QFont::toString() and
QFont::key() were modified to save the font's style name if one is
set, invalidating any stored font identifiers. QFont::fromString()
was also adjusted to accommodate the change.

Change e109b8a0f3 introduced a
performance regression when rapidly switching fonts as long as
the number of different fonts is over a relatively small number, since
the cost of fonts can be high compared to the limits set on the cache.
Since the original patch was intended to avoid exceeding the
open file limit when using Freetype on Windows, we add an
additional check on the number of engines in the cache as well
for the added, synchronous cache flush.
The limit is set to 256 to make it unlikely that it is exceeded
during a single paint event, but it can also be configured when
building Qt if a higher limit is needed.

This is a partial revert of 992f233c in Qt 4 repo. The rest of the
change cannot be reverted, since it added public API, but that
API might be useful anyway.
The patch was wrong, basically. QFont::exactMatch() should not claim
that you can get an exact match for a typeface alias. It also introduced
some weird inconsistencies: For instance, if the first font the alias
resolved to in FontConfig did not exist, then exactMatch() would return
false, even if it then resolved to the next one which existed. This
caused a test failure on OpenSuse, where the preferred font for "sans"
is Arial, which doesn't exist, so Roboto will be used instead.
[ChangeLog][QtGui][Important Behavior Changes] QFont::exactMatch() now
returns false when the provided typeface is an alias.

simply delegates to the one of QFontDef, which has been added for this purpose,
but may prove useful in its own right down the line.
The code would greatly benefit from a qHash(qreal) implementation. Lacking
this, the patch uses multiplication with 10000 and qRound64() to convert
the one floating-point property used in the hash to an integer. This is
probably the right thing to do anyway, to avoid epsilon problems.
