I run my own Qt version which isn't 100% stock anyway, so I introduced an env. 
variable check for QT_FONTCOMBOBOX_NO_PREVIEW in QFontFamilyDelegate::paint() 
which determines whether the font family and size are changed or not.

This is a user preference anyway (app devs can avoid QFontComboBox altogether as 
Konstantin pointed out), and one can assume that a dislike of font previews is 
not limited to a single app. (IOW setting QT_FONTCOMBOBOX_NO_PREVIEW globally 
should be good enough).
