  34      *
  35      * The used strategy for horizontal scrolling of the levelpack columns
  36      * is to avoid scrolling as long as the target levelpack is still visible.
  37      * The current levelpack may be scrolled out of visibility by using the
  38      * scoll buttons within this menu. But if the user changes the current
  39      * levelpack via indirect methods besides
  40      * using the levelpack menu, f.e. the jumpto command, we ensure that
  41      * the new current levelpack is visible when the menu is redisplayed.
  42      * If it is necessary to scroll we scroll only the minimum amount of columns
  43      * needed to display the current levelpack. Even on screen resolution changes
  44      * we try to keep the column of the current levelpack unchanged.
