Changed behavior when there is no pixels in the neighborhood for
...
ST_Neighborhood. It should still return an array as the pixel of
interest could have a value... just surrounded by NODATA.

Changed output array of ST_Neighborhood to have dimensions of Y,X
...
instead of X,Y. This matches that found for GDAL blocks.

determined. Added regression tests for band without NODATA.

precision array. This allows the output to be readily passed onto the
ST_xxx4ma functions.
