        Split out the renderPrivate in two methods, one for working on
        relative coordinates (relative to the viewport) and one for
        working on absolute coordinates. The latter is more effecient
        for implementing tiling, as you don't need translate the coords,
        and because it avoid clipping to the viewport.

        No behaviour changes, so no new tests.
