Move the specialized code in NEW_PICTURE_MSG_ID to setContentScrollTo so that a scroll to (0,0), whether a result of a NEW_PICTURE_MSG_ID or from an initial layout (or otherwise) is treated as scrolling to the top of the content, including showing the title bar. Scrolls to (0,1) will trigger code that animates the title bar off screen. Change-Id: Ia6db6d4620dea2bfe62407c4394a8ead38501b2f
