- Chase Camera:

Browse Source 
- Has panning bounds, zoom bounds, and general tidy up.
 - Now correctly observes the boat object rather than getting information from both the boat object AND the client yacht model.

Top Down Camera:
 - Can only pan within certain bounds now, and will continue to follow the boat regardless.
 - Can only zoom within certain bounds now.

Isometric Camera:
 - Nothing changed.
