Comment:

 Replying to [ticket:1318 pracine]:
 > Now that we have ST_MapAlgebraFctNgb we might want to provide some
 predefined user functions like ST_Max, ST_Min, ST_Sum, ST_Distinct,
 ST_Mean, ST_StdDev, ST_Range, ST_Quantile, ST_Median, ST_Majority,
 ST_Minority, ST_Slope, ST_Aspect...
 >
 > We might want to systematically change the prefix or add a suffix (I
 would suggest '4MA' i.e. 'for MapAlgebra') to the function names so we
 know were written to be used with ST_MapAlgebraFctNgb. e.g. ST_Slope4MA()

 It may make sense for ST_Slope and ST_Aspect to be their own functions
 that wrap ST_MapAlgebraFctNgb, since the neighborhood is fixed at 3x3.
