- I've corrected several areas around Braunschweig Kanzlerfeld from natural=wood to landuse=forest.
- Additionally I've tested to bring together areas like forests with highways if reasonable. Not to have a highway and next to it with a gap of a few meters a forest for example. I think it looks better if the border of the forest is on the highway. I'll check after the next render if it works out.

Edit on 03.01.2009:
The result of the above mentioned looks good. I think I'll go on like described.
