 /* PageView. What's in this file? -> quick overview.
  * Code weight (in rows) and meaning:
  *  160 - constructor and creating actions plus their connected slots (empty stuff)
  *  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,
  * and many insignificant stuff like this comment :-)
