Permute an 8x8 block according to permutation.

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!
