Well, it'd be easier because a multipoint you can dump in single points
and edit single points directly and then rejoin back and use as input.

Wait, reminds me of the same thing you can do with raster, but doing it
with raster is soooo slow (probably shouldn't be).

The other advantage of the points is that you'd be dealing with geographical
locations, not array offsets..
