Title: Prevent outlines between neighbour geometries of same layer & class from collapsing

We need to display data which is referencing roads. The roads themselves are rendered as lines and there it is nice, that between the individual road sections there is no border/outline in between, but they are „collapsed“ to one single line.

The other data is in data structure, very similar - but there we want to see exactly where one object ends and the other begins. So there we would like to see the outline „cutting“ the line.

I attached two files, one showing the current behavior which is favorable for streets and the like: ![collapsed](https://f.cloud.github.com/assets/65495/2111097/ce2ea4b4-900c-11e3-9c46-c718f410cdb6.png)

The other shows what we would like to have for our second type of data: ![not_collapsed](https://f.cloud.github.com/assets/65495/2111099/d03f12fc-900c-11e3-8fee-ee9729ec5bbc.png)
