[Mapserver-users] Layer interpolation

Has there ever been any thought on adding a interpolation object. What I 
am thinking of is the ability to have point layer and then tell 
mapserver to interpolation the data into a raster layer. The 
interpolation could be done using some fast  inverse distance weighting 
method.
example:
LAYER
    TYPE   INTERPOLATION
    DATA   point_shape_data
    INTERPOLATIONITEM"[column]"
    CLASSITEM "[pixel]"
    INTERPOLATION
           R_VALUE  4
           RESOLUTION_UNIT   meter
           RESOLUTION  5
    END
    CLASS
        EXPRESSION ([pixel] < 64)
        COLOR 0 0 0
   END
   CLASS
        EXPRESSION ([pixel] >= 64 AND [pixel] < 128)
        COLOR 255 0 0
  END
 
END
