The first argument <varname>value</varname> is the set of values (as double precision) from all input rasters. The three dimensions (where indexes are 1-based) are: raster #, row y, column x. The second argument <varname>position</varname> is the set of pixel positions from the output raster and input rasters. The outer dimension (where indexes are 0-based) is the raster #.  The position at outer dimension index 0 is the output raster's pixel position.  For each outer dimension, there are two elements in the inner dimension for X and Y.  The third argument <varname>userargs</varname> is for passing through any user-specified arguments.
