[Xastir] GeoPDF try

[Lee Bengston]

OK, got the conversions working.  Some screen shots are available via the
links below:

Screen shot 1 - the geotiff file for Leesburg, VA as displayed in the
ristretto image viewer in Xubuntu 15.04.

Screen shot 2 - the same geotiff file displayed in Xastir.  Still a decent
offline map, but it doesn't display the text as clearly.

I'll plan to provide detailed instructions for the following:

- where to download the geoPDF maps
- what Xastir needs in order to support geoTiff maps
- how to install what is required to convert the USGS geoPDF files to
geoTiff files
- how to convert the files with the applicable perl script
- where to put the maps so Xastir can use them


Best,
