Currently the flow direction decorations run in the local Y. This means that if one is creating ducts/pipes in the xy plane, the decorations are drawn in planes perpendicular to that one and than means that the arrows are not visible from a top/bottom view. By adding another set of arrows perpendicular the arrows are always visible no matter what projection is taken.

I'd like to instead investigate using local screen coordinates for this rather than this solution. But let's keep this PR open in case that isn't an option.
