I can't remember why it was changed either, but I for one would dislike
it if scrolling the image with the wheel would suddenly switch to the
next/previous page: when I scroll it's usually because I want to center
the image differently.
So I do think that we need 2 modes: a continuous mode and the current mode.

I can't think of any reason why that would be a problem.  OTOH the
scrolling commands will need to be changed, and that may prove
more difficult.

At least for PDFs, it should be fairly easy to adjust the current code
to DTRT.
