Does this mean an additional fringe is necessary that doesn't scroll?

Then we have the same question as with multiple header lines:
whether to allow multiple fringes and header lines or implement them
as true windows placed on the left or on the top of the base window.

Using windows will allow implementing emulations of the scroll bar
like minimap.el, etc.  I'm not sure whether this is possible to do
with additional fringes?
