• Train stations and subway stations will be drawn.
  
• Memory usage decreases.
  
• Added setting to not use temporary bitmap of buildings, tracks and roads on screen display. ("View" - "Disable Bitmap Cache")
  Memory usage further decreases. Even when you zoom in on the map, it will be displayed cleanly. But slow. It does not affect output result to the file.

- Add: Forest
- Fix: several error handlings
- Fix: Support for city name with characters that can not be used as file name

FIX:Now some tetrapod assets are ignored.
