1231	refMatrixId can become negative	jackh		"Equation 7-35 states:

{{{
refMatrixId = matrixId − scaling_list_pred_matrix_id_delta[ sizeId ][ matrixId ] * ( sizeId == 3 ? 3 : 1 )
}}}

and the specification constrains scaling_list_pred_matrix_id_delta as follows:


   The value of scaling_list_pred_matrix_id_delta[ sizeId ][ matrixId ] shall be in the range of 0 to maxMatrixId, inclusive.

The combination of these two allows refMatrixId to become negative. Perhaps the constraint on scaling_list_pred_matrix_id_delta should read:

   The value of scaling_list_pred_matrix_id_delta[ sizeId ][ matrixId ] shall be in the range of 0 to sizeId==3?(matrixId/3):matrixId, inclusive.
