 Replying to [comment:8 dustymugs]:
 > Added scalex and scaley.  Will need to write a lower-level function to
 get the band pixtypes of a raster quickly.

 I'm afraid there is no way to do that quick. Maybe for the first band but
 not for the other bands. Remember when you wrote deserialize_header...
 Would that mean that everything has to be deserialized to determine all
 the pixeltypes and the nodata values of all the bands of all the tables?
 Scary...
