Probably something custom.

For vertical scrolling, you just have to do a wincopyrectangle to move
the image, then copy (from offscreen) or rerender the band exposed by
the scrolling.

(I've implemented this horizontally and vertically in PiNGer - not the
best code but it works).

Rendering speed would be the limiting factor.
