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!
