[mkgmap-dev] issues with tile boundaries

Hi Gerd,

I have another related (cosmetic) issue with tile borders which exists already some time (november 2011) but maybe you can have a look at it?

You can see the issue on every map in Mapsource when you select the tiles. They get a yellow border, but not only in the outlines, but sometimes inside the tiles too. 
See https://dl.dropbox.com/u/64716698/OSM/mkgmap/tileborders1.jpg

In Basecamp, you can see it as thin blue lines, when you browse a gmapsupp.img from micro Sd card or GPS:

When you zoom on it, sometimes the map disappears, but the maps are still routable.

As far as I know, it is not style or typ file related.

It happened after this patch was committed:

It fixed the transparency of the gmapsupp.img and "ghost shading" of the overview map in mapsource.
