Commit [r4036]  Maximize  Restore  History

Never refresh the background when refreshing an invalid rectangle on the screen. Since the entire rectangle is always refreshed, there's no benefit to refreshing the background as well--doing so only slows down the repainting and adds more potential for flicker. In truth, this change has little practical benefit.
