Please do.  Any feedback would be appreciated.  There are other approaches  
we could take, such as bringing in the far clip plane dynamically or  
living with the reduced z buffer precision of a very close near plane, but  
each has their drawbacks.  Keep in mind that when zooming in on an object,  
the object itself is not always the user's point of interest (which  
admittedly is a problem with the FOV zoom approach).

For those unfamiliar with the mathematics of z buffering, wikipedia has a  
decent summary:

Yes, please stick to XUI strings for new UI.  Don't worry about cleaning  
up existing files, since I plan to remove them in our cleanup pass anyway.
