The default font is no longer handled like a custom style sheet that overrides everything, but as the initial value. This is the same behavior as in web browsers. And it allows the theme to actually use the 'font-family' and 'font-size' properties. Of course, a well behaved theme will respect the setting as much as possible and for example use relative font sizes (which aren't yet supported, but will be soon).
