<!-- 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.
