+ *
+ * Objects when inside a scroller can scroll, but this may not always be
+ * desireable in certain situations. This allows an object to hint to itself
+ * and parents to "not scroll" in one of 2 ways.
+ * 
+ * 1. To hold on scrolling. This means just flicking and dragging may no
+ * longer scroll, but pressing/dragging near an edge of the scroller will
+ * still scroll. This is automastically used by the entry object when
+ * selecting text.
+ * 2. To totally freeze scrolling. This means it stops. until popped/released.
