// Tests MCoeControlBackground interface.\n
// Parent controls can elect to take responsibility for drawing the background for their child
// controls.\n To achieve this, they should aggregate an object that implements this interface.\n
// CCoeControl::SetBackground() accepts the object and sets it as the background drawer.\n
