Currently special renderings might not always respect Nodata value set on original GDAL dataset while doing the computation. Check each special function if respects nodata and does not involve them in computations.

Example: pansharpen or DEM visualizations. Currently interpolate + pansharpen do not work together wrt nodata setting.
