Review request for Viewer.
Changes
-------
corrected the jira link - just put the id in, not the url
Summary
-------
I looking at the code, trying to find out where/how to add a new feature, when I tripped across one of these and it lit my mental warning bells off. Vector distance comparisons should, IMHO, always be done squared. So I did some greppin, manual analysis, and some careful modification, and here's the result.
This addresses bug VWR-25126.
http://jira.secondlife.com/browse/VWR-25126

Testing
-------
Compiled a test viewer and used it, undertaking some of my normal activities. Results felt good, but are currently anecdotal. Any suggestions on how to properly measure this (or even some actual measurement from those already instrumented to measure these things,) would be great!
Thanks,
Cron
