This wasn't correct. Padding is already accounted for:

  scale = (width - (pages_per_row - 1) * padding) /
          (pages_per_row * cell_width)

If you add padding on the denominator, you end up with black margins on
the sides of the window, which isn't what padding is for (i.e. insert a
gap between rendered pages), and defeats the purpose of a "best-fit".
