The ForceIntegerMetrics flag was added in Qt 4.7 specifically because
of WebKit, which was rounding text metrics and getting mismatches
with the underlying font engine whenever it supported fractional
advances. For backwards compatibility with how the CoreText engine
worked before this, we added a flag to allow rounding all metrics.
Rounding advances gives very broken rendering and is hopefully not
used by anyone anymore, so lets remove this flag in Qt 6.
As for OpenGLCompatible, this flag is not used anywhere. I am
not exactly sure what this flag did, but all fonts are
"OpenGL-compatible" at this point.
[ChangeLog][QtGui][QFont] Deprecated QFont::ForceIntegerMetrics
and QFont::OpenGLCompatible, with the intention of removing them
in Qt 6.0.0.
