 -- nodatanodataexpr text - Expression used when both pixel values are nodata values or absent.\r

 -- Further enhancements:\r
--- -Optimization for UNION & FIRST. We might not have to iterate over all the new raster.\r
--- -Make the function being able to look for neighbour pixels. Ex. rast1[-1,1] or rast2[-3,2]\r
--- -Make the function to work with neighbour tiles pixels.\r
+-- -Move the expression parameter in seventh position just before other expression parameters.\r
+-- -Optimization for UNION & FIRST. We might not have to iterate over all the new raster. See st_mapalgebra_optimized.sql\r
+-- -Add the possibility to assign the x or y coordinate of the pixel to the pixel (do the same to the one raster version).\r
 -- -Resample the second raster when necessary (Require ST_Resample)\r
 -- -More test with rotated images\r
