Map only covers 1/4 of the entire map

I expanded the world to be 4x it's normal size of 1600x960 (the size of the grid image).
Now it is 6400x3840. I had a generation, but it was laggy and didn't work for all clients. Now the image doesn't cover all of the playable space.

Original Issue:
To generate the map, I just layer the background multiple times and save it's data as an image.
This is quite costly as it causes the browser to freeze while it does it.
I will attempt to see if a single larger image will be a better solution.

I'm removing this for now and changing the issue from "Map generation freezes the browser for a few seconds" to "Map only covers 1/4 of the entire map."
