[Xastir] Goodbye GeoTIFF, Hello GeoPDF

[Kurt]

I believe the discussion was from December and I was able to get the script going on a couple of laptops with help.  I'd recommend at least a quad coreas an old dual core took forever to do one conversion.  I downloadedsome maps through a wide bandwidth link during a weekend at work and took the files and placedthem on the quad core and old dual core.  Takes a long time for screenchanges on the dual core and the GeoTiffs are mixed in with the old Tigeror Cloudmade maps I have lying around. They look nice at all except veryclose zoom levels.

Xastir has a script that uses gdal to convert GeoPDF to GeoTIFF.  Tom Russo
wrote it a few years ago and refined it much more recently.  There was
quite a bit of discussion about it not too long ago.
