Subject: Do not rely on the list of standard font sizes for QFontDialog.

QFontDialog should always show the correct size, even if the size
is not available in the list of standard font sizes. Native font
dialogs across common platforms show the correct size at all times.

Inside init() function, the size list requires proper initialization
since the initial value of size is zero.

Task-number: QTBUG-10317
