permute block according to permuatation.

Parameters:
last last non zero element in scantable order
permute block according to permuatation.

Parameters:
block the block which will be permuted according to the given permutation vector
permutation the permutation vector
last the last non zero coefficient in scantable order, used to speed the permutation up
scantable the used scantable, this is only used to speed the permutation up, the block is not (inverse) permutated to scantable order!
