 I know the -cutline option since the Hackfest when Tim told me about it.
 Thanks for reporting it, I forgot to add these information to this ticket.

 > would be nice too to add this options too in gdalwarp
 So,
 1. improving the clipper (clipping based on a shapefile mask)
 2. add the -cutline option in the gdalwarp tool too.
