[amenity-points] More rendering of bus stops

Description

This bug is about the Mapnik style rules used to generate the default OSM slippy map.

Currently bus stops are shown at zoom levels 17 and 18. I would like to suggest:

Zoom level 16: show bus stop as a small blue dot (same colour as the existing bus stop icon, but smaller).

Zoom level 17: as at present.

Zoom level 18: additionally show the name of the stop.

Since the Naptan import in the UK there are often clusters of bus stops with the same name, stored in OSM as a relation. The icons for each stop should be shown individually, but the name should be printed on the map just once.

Examples of such a relation? Will the separate bus stops also carry the same name=* ?

Have a look at relation 206318, added by the Naptan bus stop import in London. It has a name and contains two bus stop nodes.

Sometimes the individual nodes have a 'local_ref' or 'ref' attribute, which in London is a single letter. This is a marker shown on the bus stop to help you find the one you want, in places where many bus stops are near each other. This 'local_ref' could be shown on the individual nodes at zoom level 18.

It seems that from the Naptan import, the individual nodes also have a name tag, but I think that if the stop is part of a relation it would be better to use the name of the relation.

I can see little blue squares appearing at zoom level 16. Thank you!

To give an idea about how the 'local_ref' might be rendered, have a look at <http://www.tfl.gov.uk/tfl/gettingaround/maps/buses/pdf/cityoflondonnightbuses-13504.pdf>. The letters 'A' to 'Z' match the one shown at the top of each stop, as in this illustration: <http://upload.wikimedia.org/wikipedia/commons/a/a8/BUS_STOP_LONDON_v2.jpg>. Not every bus stop has such a letter - only where there are several close together.

I don't know whether other cities use a similar scheme or if it's tagged using 'local_ref' or 'ref', but there is certainly a lot of bus stop data in London like this.

One snag is that the dots for bus stop are easy to confuse with the dots for natural=tree, for example in <http://a.tile.openstreetmap.org/16/32749/21786.png> which comes from <http://www.openstreetmap.org/?lat=51.52738&lon=-0.1019&zoom=16&layers=B000FTF>.

To my eyes, the 'tree' dot looks more blue than green, especially when rendered against the cream-coloured background in this tile. Perhaps natural=tree needs tweaking to be a darker, greener kind of green?
