[sis] 06/06: Temporarily enable the use of `ResamplingGrid` for testing purpose. Unconditional enabling of this optimization can actually slow down the rendering of zoomed image because the grid is computed for the full image instead than only the visible portion. A future version should enable this optimization only when we know that most of the image surface will be used.

    Temporarily enable the use of `ResamplingGrid` for testing purpose.
    Unconditional enabling of this optimization can actually slow down
    the rendering of zoomed image because the grid is computed for the
    full image instead than only the visible portion. A future version
    should enable this optimization only when we know that most of the
    image surface will be used.
