Another batch of warning fixes
Fix buffer overrun with long field values.
Fixed all warnings in asf_meta... had to disable one :(
Do not use errno to detect failure to parse a value, not reliable.
Function was not returning success, causing unexpected processing failures
Initialize center point to NAN, just in case.
Last warning (at least when compiling with gcc 4.1.2 ...) eliminated.

This code will have to be revisted at some point-- right now it is not
being called.
New "outline" feature in asf_view, shows outlines of other loaded images.
