Re-worked to handle proportional fonts and scale with font size changes.  To bad we don't 
scale the symbol but I'm not about to open that can of worms.

Tested with a view from Alaska to Cuba and over six thousand visible stations.  All text 
elements turned on, and no easily observable memory issues.  Yes it took about four seconds 
to redraw when you switch Station Styles but displaying that many is a bit impractical.

Those feeling adventurous have at it.
