[mkgmap-dev] overview2 branch

Wed May 29 22:38:43 BST 2013

Hi Steve,

I changed it because of that screenshot and the remarks from Felix:
http://gis.19327.n5.nabble.com/Overview2-branch-options-file-typo-tp5759855p5759898.html

I wanted to have up to 8 levels for both the normal img and the overview
map, and I found no problem with the overview map starting at level 0. 

I guess it would not be a problem for anyone to go back to the limit of 8
levels?
