That op has been removed, I have some experimental (not commited to
git yet) code that revisits the ideas that originally were employed in
that op, another place where some of the concepts of this op is
manifested is in the gegl:stress op (which is stochastic and noisy for
low iterations/reasonable processing times.)

GMIC and resynthesizer do some of these things with some approaches,
netiher of them do it as GEGL ops nor are they usable for GIMP or
other applications as GEGL operations. Thus from a purely GEGL based
view no such functionality is available.
