+-- neighborhood tile support --

+When processing a tile's pixel in a neighborhood calculation, there needs to
+be a way to get the neighboring tiles so as to provide the neighboring pixels
+of the pixel being processed.  This is a difficult question because rasters

+a tablename and raster column is inappropriate as the table and raster column
+could be more complex, such as when a table contains daily observations of a
+temperature surface.
