Comment(by strk):

 Good question. For geometry ConvexHull(EMPTY) == EMPTY. The type of EMPTY
 (in geometry) is taken from the type of input, but I think that's pretty
 arbitrary. For Raster if you take the EMPTY path I'd use POLYGON EMPTY, as
 I think a raster's convexhull is _always_ polygonal in other cases, is
 that right ?
