Lines outside of map viewport behavior

From @mivanov:

lines_within makes things disappear when they should be visible, like say a long street/trail that is partially offscreen. Might be ok if this is needed for performance, but the user experience is a little confusing.

@philipn:

This was the intended behavior. The scruz map was an unusable mess otherwise. What would be a workaround? Could hide lines once they are a certain distance away and fade them out (though I think they already may be fading, need to check)

@mivanov:

I don't think they're fading now, that might help. But it's prob not a big deal and can be as is for now. If we had some kind of filtering the "intersects" logic would be more accurate so we can revisit then.
