test case

Open the attached test case in Safari. Enable the "Never use font sizes smaller than:" pref in Safari preferences.

Result: The text is displayed with a very big font. Other examples are http://dbaron.org/log/20110225-blur-radius and http://orbis.stanford.edu. WebKit renders the text of these websites very badly if this perf is enabled.

The bool param makes it hard to read at the call site. An enum would be better.

Typo: DonNot.

I think the argument name should be minimumSizeRule rather than minimumForFontSizeRule. Other argument names just say Size, not FontSize, and the For is not needed.
