I propose to make `public` the [RoundaboutInstruction.getExitNr](https://github.com/graphhopper/graphhopper/blob/master/core/src/main/java/com/graphhopper/util/RoundaboutInstruction.java#L76) to be able to handle more flexible the `RoundaboutInstruction` (like the others) by getting its elements.

It would be also helpful if the `RoundaboutInstruction`'s `finished` and `continuedStreet` variables get public get methods, since they participate in instruction building.

I know you have mentioned that the roundabout instructions are to be improved. Because right now do we really need the instruction with [0 exit](https://github.com/graphhopper/graphhopper/blob/master/core/src/main/java/com/graphhopper/util/RoundaboutInstruction.java#L137)? Isn't confusing for the user?

VTM [does not allow](https://github.com/mapsforge/vtm/blob/master/vtm/src/org/oscim/theme/XmlThemeBuilder.java#L642) dash values < 1 because of OpenGL restrictions. Also this error message does not seem to exist (?) in VTM code. So how this could happen?...

@eddiemuc this is a nice idea. Do you mean like this? https://github.com/mapsforge/vtm/pull/1083 Mapsforge should already be ok?

Do you want to display thousands of markers on the map with the same performance? They won't even be easy to read. OpenGL rendering is real-time. You could examine other...
