After implementing more smooth scrolling, we could later add
a third value (e.g. `smooth') to the customizable variable
`doc-view-continuous-mode'.  But with a minor mode this would not
be possible.  Or when somebody will request to not allow SPC and DEL
to scroll to the next/previous page, we could add a fourth value.
IOW, with defcustom we have more degrees of freedom.
