276	* This function derives the prediction samples for the angular mode based on the prediction direction indicated by
277	* the prediction mode index. The prediction direction is given by the displacement of the bottom row of the block and
278	* the reference row above the block in the case of vertical prediction or displacement of the rightmost column
279	* of the block and reference column left from the block in the case of the horizontal prediction. The displacement
280	* is signalled at 1/32 pixel accuracy. When projection of the predicted pixel falls inbetween reference samples,
281	* the predicted value for the pixel is linearly interpolated from the reference samples. All reference samples are taken
282	* from the extended main reference.
