    DrawingCtx.initial_transform_with_offset - remove this function; use the plain initial transform
    
    Now that draw_tree() creates an initial transform and viewport so that
    the latter has (0, 0) at the origin, we don't need to offset the
    initial transform passed to CompositingAffines::new().  We can use the
    plain initial transform as computed by draw_tree() at the beginning of
    the drawing process.
