SVN_SILENT Started writing code that would display a thumbnail of a

Browse source 
window in the middle of the screen if it was offscreen when the
highlight window effect was activated. After getting half way through it
however I determined that it was a useless feature so instead of
deleting the code that was already written I am just commenting it out.
If anyone can find a purpose for this please let me know your ideas.
