  *  70  - DocumentObserver inherited methodes (important)
  *  550 - events: mouse, keyboard, drag
  *  170 - slotRelayoutPages: set contents of the scrollview on continuous/single modes
  *  100 - zoom: zooming pages in different ways, keeping update the toolbar actions, etc..
  *  other misc functions: only slotRequestVisiblePixmaps and pickItemOnPoint noticeable,
