 * of the block and reference column left from the block in the case of the horizontal prediction. The displacement
 * is signalled at 1/32 pixel accuracy. When projection of the predicted pixel falls inbetween reference samples,
 * the predicted value for the pixel is linearly interpolated from the reference samples. All reference samples are taken
 * from the extended main reference.
