Updates the cc RTree class to handle overflow:
  - GetBounds becomes GetBoundsOrDie and can only be called when
    has_valid_bounds().
  - All other functions are unchanged, operating correctly, but less
    efficiently, when !has_valid_bounds().

Updates DisplayItemList to handle cases when !has_valid_bounds().
