QFontEngine: Cache whether or not a font can be smoothly scaled
This will be used by QtQuick to correct a performance regression introduced by
592614ea3ecd90ede2ae1b8e6579d1b898f474ec -- QFontDatabase::isSmoothlyScalable is
quite computationally expensive; and now it is unconditionally expensive
regardless of the platform.
