[Xastir] Script to cache some maps

[David Ranch]

Hey Curt,

Could you send us a screen capture of what your rendered ESRI Shapefile 
data looks like?  I personally don't necessarily need ultra pretty tiles 
but I definitely don't need the complexity and resource hungry 
requirements of setting up a local tile server.  If my old little Garmin 
handheld GPS can do maps pretty well from a little SD card, why can't 
Xastir do this too?  There has to be a decent compromise somewhere in 
this whole thread.
