[roads] Rendering of highway=path with access=no is inconsistent

Hi,

mapnik shows highway=path with access=no in zoomlevel=13 and 14 as normal path. Only in higher zoomlevels the rendering is reflecting the access=no feature. Example:

Wrong rendering:
http://www.openstreetmap.org/?lat=51.8043&lon=10.6412&zoom=13&layers=M&way=28067282

Right rendering:
http://www.openstreetmap.org/?lat=51.8043&lon=10.6412&zoom=15&layers=M&way=28067282

I see two ways to fix this issue:

1. Do NOT render those pathes in zoomlevel 13 + 14 at all
2. Render those pathes with red markers reflecting access=no in ALL resolutions

Rationale: Users of the map might be confused by a way which seems to exist at first view but becomes unusable at second view (if they do such a second view at all and do not simply trust that there is a usable way.

Specific rationale for this very example: The rangers of the national park "Hochharz" are quite pissed of about OpenStreetMap advertising trails which should not be used.

Kind regards and thanks for maintaining mapnik

    Andreas.
