+  //     you try to enumerate with EnumerateFonts, you get an array of all
+  //     fonts in the systems (This also breaks our fonts dialog).
+  // (c) In Gecko, each langauge has a distinct serif and sans-serif font
+  //     preference.  Safari has only one default font setting.  It seems that
+  //     it checks if it's a serif or sans serif font, and when a site
+  //     explicitly asks to use serif/sans-serif font, it uses the default font
+  //     only if it applies to this type.
+  // (d) The solution of guessing the lang-group out of the default charset (as
+  //     done in the old Safari migrator) can only work when:
+  //     (1) The default charset preference is set.
+  //     (2) It's not a unicode charset.
+  // For now, we use the language implied by the system locale as the
+  // lang-group. The only exception is minimal font size, which is an
+  // accessibility preference in Safari (under the Advanced tab). If it is set,
+  // we set it for all languages.
