[OSM-talk] osmarender slippy map rendering

Yes, I realise it is intentional, but I don't think it quite works, for the
reasons I gave.
I think the transparency is great, makes the map much more readable, and I
don't think there's too much of a problem having the place names disappear
at very high zoom. The problem is that _some_ place names disappear, and not
others, and it happens too early.
So my suggestion would be (a) to have either all or no place names at any
particular zoom, not a mixture; (b) I think I wouldn't make the text enlarge
quite so much at the higher zoom levels where it is visible and (c) I'd keep
all the names at zoom 14 and 15 too. (Once the street names start to come
in, then the town and suburb names could go).
I can see that for large towns (say somewhere like St Albans or Chester),
the town name may be off the area being viewed, but for smaller towns like
these, where you can see the whole or most of a town, but not its name, I
think it is misleading.

(and switch to osmarender base layer)
This shows the town of Whaley Bridge with its suburb Horwich End.
Zoom in to level 14, and Whaley Bridge disappears altogether (even though
its entire extent is visible), but Horwich End is much bigger. This gives
the impression that the place is called Horwich End, not Whaley Bridge (the
smaller red Whaley Bridge is the name of the railway station, which adds to
the confusing impression).
Browse a bit further east and the name of the larger town of
Chapel-en-le-Frith is also not visible except as the name of the railway
station (which is actually well out of the town).
