Remarks
Called when a child of this group wants a particular rectangle to be positioned onto the screen. ViewGroups overriding this can trust that: <ul> <li>child will be a direct child of this group</li> <li>rectangle will be in the child's content coordinates</li> </ul>
ViewGroups overriding this should uphold the contract:
<ul> <li>nothing will change if the rectangle is already visible</li> <li>the view port will be scrolled only just enough to make the rectangle visible</li> <ul>
