[Xastir] New Online Maps in Git (Canada & U.S.)

[David Ranch]

Hey Curt,

Playing around with the new maps say aerial.geo, it works from a zoom 
level of 1 to 64 but with a larger zoom level like 128, the screen is 
black except for the various APRS objects when zoomed a bit.  Other maps 
show all grey.  Does the black vs. grey have a significance?

    National.geo        - the screen is light grey except for the 
various APRS objects
    Sub_National.geo    - the screen is light grey except for the 
various APRS objects
    Sub_Regional.geo    - the screen is light grey except for the 
various APRS objects
    Aerial.geo:         - works for zooms 1 to 64 then the screen is black
    ShadedRelief.geo    - works for zooms 1 to 8 then the screen is 
light grey
    Topo1-10.geo       - works for zooms 1 to 8 and then the screen is 
light grey
    TopoRelief1-78.geo - the screen is light grey except for the various 
APRS objects

Other maps like Regional, Coutours, Hydrography, and transportation work 
fine.  Maybe the black vs. grey behavior is known in Xastir but since 
I'm still new to it, I'm not aware of it.  Maybe there is a way to 
display in the UI something like "map not available at this zoom - try  
1 to 64".  That would be a lot more user friendly.

I'm also seeing with this new Xastir version when loading these new 
maps, it's not saying "loading tiles.." in the lower left.  It says "Map 
not found in cache...".  Is there a way to make this a little more 
intuitive?  Maybe change this to "Loading map from network..." would be 
more intuitive?


Thanks again for adding these new maps!
