/**
 * This subclass of TextView is designed to get aaround a bug in Android 4.1 and 4.1.1, documented here:
 * 
 *     http://code.google.com/p/android/issues/detail?id=34872
 * and here
 *     https://code.google.com/p/android/issues/detail?id=35412
 * 
 * It should have no effect *except* for very specific books in the above-mentioned versions of Android
 * 
 * NOTE:
 * It should only be needed for TextViews that are wrapped and have MetricAffecting spans (eg. URL, bold, emphasis).
 * Currently this is limited to the book description field.
