[Xastir] Georeferencing shapefiles.

[Gerry Creager N5JXS]

There's a special place in hell for people who create purely arbitrary 
"geospatial" data and make it available to others with poor metadata.

It's possible to take such a file and georeference each polygon vertex, 
line end-point and point-value.  It is, however, a PITA.

Much better to seek a raster and get it georeferenced with good 
underlying map data, then digitize the points along the map.

When's this race?  I can see if I can remember to bring home a MapInfo 
system and look at these things...  however it'd be easier and faster if 
you were looking over my shoulder while I was trying, as you're the 
local expert on the terrain.
