REVISION SUMMARY
  BUG: 395028
  FIXED-IN: 5.12.6

TEST PLAN
  Compiles. Scroll bars hover fine in both widgets and QML apps.
  
  Should this perhaps use
  
    bool widgetMouseOver( ( option->state & State_MouseOver ) );
  
  like in `scrollBarArrowColor` so that it maybe gives a hover effect in this case?
