I think what we need with polygons it this: 
- when setting the grid fields outside of the polygon to 0, splitter also
must make sure that no grid field inside the polygon is 0
- having done that, splitter can activate trimming

This is a simple change, the result is the splitter_auto_trim.kml in the
attached zip
hdach2.zip <http://gis.19327.n5.nabble.com/file/n5737726/hdach2.zip>  

To avoid holes, something similar could be done also if no polygon file is
given.
Wouldn't that be much better?
