I have to admit that I did not understand this proposed use of
REPLICATE:

>> sometimes (replicate({temp:input},newsize)).(0) is faster then rebin

But it brought me a related question in mind: does IDL have a
"REPLICATE" function for vectors instead of scalar values? I am using
REBIN, but REBIN is thought for more advanced uses and probably
suboptimal for a "replicate-like" use... right?
