Comment(by dustymugs):

 The convention is the number of pixels from the reference cell.

 So, specifying ngbwidth = 1 and ngbheight = 2 of ST_MapAlgebraFctNgb()
 would mean a 3 x 5 neighborhood.

 {{{
 1 1 1
 1 1 1
 1 0 1
 1 1 1
 1 1 1
 }}}

 Is this for 2.1 or 2.0?  The title seems to indicate 2.1 while the
 milestone is set for 2.0.4
