title: What automatic overdraw elimination capabilities does Android provide?
body: <p>Romain Guy mentions that automatic overdraw elimination was introduced in Android 4.4/5.0 (see <a href="http://www.curious-creature.com/2015/03/25/android-performance-case-study-follow-up/comment-page-1/#comment-52600">http://www.curious-creature.com/2015/03/25/android-performance-case-study-follow-up/comment-page-1/#comment-52600</a>) but I haven't been able to find documentation or talks referring to it. Does anyone know any details?</p>
