[mkgmap-dev] Small holes in boundary coverage

From GerdP gpetermann_muenchen at hotmail.com on Sat Mar 17 18:42:33 GMT 2012

I fixed one problem in BoundaryQuadTree which removed most of the holes, 
but I still find one in africa which is not shown in with trunk version, so
will continue tomorrow ...
