Replace scrolling methods with enum

The different scrolling methods added a bunch of boilerplate where the
call was just forwarded to the next struct, this has been removed by
making the scroll amount into a struct.

Now everything is called through one method and the parameter decides
how far the viewport should be scrolled.
