  <!-- Test that an overscroll past one end of a viewport is
       rendered as having the content create a gutter, and that
       the overscroll is reduced by some factor such that
       a 100px scroll must produce a rendered translation of less than
       100px.

       Current overscroll physics mean that an instantaneous overscroll
       by 200px produces an 8px gutter. This is governed by the logic in
       Axis::ApplyResistance(); if that logic is changed, this test will
       need to be modified to account for the new result.
