Elevated way on bridge

[poppo]

Hi!

I make patch which allow us to build elevated way on bridge!elevated_way_on_bridge.patch

we can build elevated way even on the bridge tiles like this:


technically, we check height of the way for slope tile, and use get_weg_hang().

The elevated way building is to be completely renovated "soon" anyway, so allow more than single height elevated ways. I will look into the patch. But since building on elevated ways is allowed, building on bridges should be allowed too.

Long term, we should probably have an elevated waybuilder instead patching everying onto the poor normal waybuilder ...
