[mkgmap-dev] r4015 in dem-tdb branch implements --x-overview-dem-dist

Hi,

Gerd has published formula for his parameters, you have to multiply your 
dlon by 2^32/360. Value dlon=0.00027761 is equivalent of about 
x-dem-dists=3313.

Basically 1" arc DEM ~ 3314, 3" arc DEM ~ 9942.
Or so I hope, I haven't tested.

Andrzej
