Currently they are combined on the server to create a composite image using some GD library I think. This seems to works very well and avoids duplicating the most compute intensivepart of generating a map tile.Yeah it would be neat to render a captionless layer in mapnik and then overlay text on it. Can mapnik support that? I'd have thought adding any sort of text to the map might have implications for the rendering itself.
The problem is being able to do the text collision avoidance stuff against non-text features, hence why it's not been done before.
