 Discussion initiated in #595 and transferred here in order to close #595.

 The main debate is about requiring same alignment of the source and target
 rasters. Not requiring same alignment implies having to (re) sample the
 source raster and this overlaps with the ST_Resample series of functions.

 I would now tend to make it simple and authorize copy only from well
 aligned rasters... and hence to make it behave like the plpgsql prototype.
