 * An improved version of DrawerLayout that will ensure that a locked open DrawerLayout can be used without capturing all touches into the client
 * area.
 * <p>
 * To activate, call {@link #requestDisallowInterceptTouchEvent(boolean)} on the layout. Note that this should only ever be done in case when
 * the drawer is to be locked open.
