Scale to legibleScale if double tap would barely zoom in from zoomed out state.
The motivation for this is for double tap to zoom in when viewing an image, (no html) which we believe to be more user friendly than just silently doing nothing.
It could potentially be a slight change in behaviour in other cases as well (text spanning all the way from left edge to right edge) though we haven't noticed any problems like this in practice.
