<!--
    The 'Classic' Compositor pipeline imitates the rendering pipeline that was
    used before multi-pass rendering was introduced, with the added feature of
    optional shadow mapping.
    The precision of the Z-buffer deteriorates with huge near-far spreads, so
    two passes with different depth ranges are used to avoid Z-fighting and
    other unpleasantness.
