static

This table is used for retrieving the current intra type based on its neighbors and adjustment provided by code read and decoded before.

This is really a three-dimensional matrix with dimensions [-1..9][-1..9][0..9]. The first and second coordinates are determined by the top and left neighbors (-1 if unavailable).
