Implement a real Private Browsing Mode condition by changing the API/ABI;
This solves Tor bug #9701, complying with disk avoidance documented in
https://www.torproject.org/projects/torbrowser/design/#disk-avoidance.

4 div { font-size: 12px; width: 450px }

7 In a 450px container, the minimum font size at 15em per line is 30px.
8 This means we map 0px-45px into 30px-45px, so 12px gets mapped to 34px.
9 However, because we've enabled the maxRatio at a value of 2.0, the mapping
10 function, which would normally return 34px/12px, or about 2.83, now
11 returns a ratio capped at 2.0, thus the actual font size is 24px.
