I would also like to be able to adjust the aspect ratio of my
cylindrical projections in the Hugin interface.  Right now, it is target
h/v fov and target h pixels; it should allow target v pixels to be
overridden.  Otherwise, to target certain print sizes I have to render
larger than I want (sometimes exceeding memory) and squish it down
afterwards.
