More work on the cities functionality. Still has a bunch of wierd stuff like:

- sometimes it will offset the map, reulting in a cutoff and all of the cities are out of place (they are not offset)
- sometimes the image will be some other window or something
- sometimes the map image is offset so that the original map is centered (ie the right side is alaska, the left is siberia) instead of being focused on the 'day' part of the map
- sometimes the image is just black or sometimes it's random colors.
