[mkgmap-dev] Error in mkgmap r-3676, wrong preview generation

An update on the problem.

The contour line tiles have the levels 0:24,1:23,2:22,3:20,4:18
whereas the content tiles have levels of 0:24,1:22,2:20,3:18,4:16,5:15

The first tile encountered determines the levels in the overview map
and so the overview maps are different.  It is surely a bug that the
map outlines are wrong and so I will look at this next.

However I am not sure what the full solution is though as there are
other noticable problems, as the overview map is going to be wrong for
one set of tiles whatever is done.  Perhaps mixing tiles with
different levels should not be allowed?
