MoveScroll( ... ) does not support jumping long distances

If you use MoveScroll to jump more than 1 tile at a time, it will not load in tiles for the rows you skip over.

For example, this is the result of scrolling by 16 pixels at a time:

The functionality is required for maps the don't start in the top left hand corner of the map.

I made a scroll to and force redraw function when using the ~2018 version of ZGB, the general idea probably still applies. There may be more efficient ways to do it and it might need some adjustment for modern zgb, not sure.
