- Check all 4 viewport corners before drawing fog
- If entire viewport is within revealed area, skip fog entirely
- Prevents polygon rendering artifacts at high zoom levels
Building animation:
- Changed range from 75-125% to 100-150%
- Buildings now grow up to 50% taller but never shrink below normal
