  56.           The IIR Gaussian Blur plug-in acts on each pixel of the activ layer or selection, setting its 
  57.           Value to the average of all pixel Values present in a radius defined in the dialog. A  higher 
  58.           Value will produce a higher amount of blur. The blur can be set to act in one direction more than 
  59.           the other by clicking the Chain Button so that it is broken, and altering the radii. It is well 
  60.           adapted to scans and photos with smooth color transitions.
