That's is good that we've identified the problem.  The suffix -mode
suggests that it's a mode while it is not.

In one of my intermediate versions I named this variable
doc-view-continuous-level that I think is an equally bad name :-)

So I installed a patch that simply removes the suffix -mode
to use a simpler name `doc-view-continuous'.

Yes, now `doc-view-continuous' can be customized and also its value
can be selected from the menu and saved as the default value.
Later we could add more values such as "Smooth" for smooth scrolling
and "Restrictive" to not jump to the next/previous page on SPC/DEL.
