Subject: [PATCH] GCS GPS Display: Noticed redrawing got real slow if I left
 the GPS Display running for a while. I'm blaming that on the text area
 filling with a million lines, though that still needs to be confirmed. So I
 added a arbritrary 200 line limit, after which lines at the top start
 disapearing. Seems sensible anyways :)
