1. QtFontStyle::Key comparison should either use styleName or
style, etc., but not both.
2. When initializing a QFont from QFontDatabase::font(), style
and weight parameters should always be set even when we found
a match styleName, in case these parameters will be used for
comparison later.
3. Move styleName out of QtFontStyle::Key so that the code can be
clearer and more explicit.
