Where's the difference, except that you could scroll the margins if you
wanted to do so?  Implementation-wise, the difference is that Nakatani's
current approach simply uses the image slice for the geometry, your
rectangle approach requires another buffer-local variable.  And since
slices are there anyway, I prefer making fitting functions do the right
thing in that scenario.

You can already zoom and hscroll until you have the visible rectangle
you like to have, and all doc-view navigation commands preserve the
hscroll.
