All of the scaling options preserve the aspect ratio (i.e. shape) of the
image you are printing.  If you provide a 1x1cm image, it will get
scaled up to ~21x21cm on A4 paper, etc.

Right, and as I've pointed out before, this just isn't a use case we
are particular interested in adding at this time.  There are plenty of
apps that allow you to do this already, such as Gimp, xv, eog, etc.
