Arrows to scroll. IMPORTANT: A 20x20 world will take a long time to load (about 2 minutes with a max height of 4) but it will still scroll very smoothly. On the upside, the world is 8000x8000 blocks! Also, large max heights on small world sizes look a little strange...
All original. Credit for use, please. 6/23/15 - Added in a better progress bar that doesn't lag.
