[80n]

Hi Ben
The reason primary and trunk render in dfifferent colours at different zoom
levels is because zoom levels 14 through 17 are not finished yet.

Zoom levels 12 and 13 were fixed up a while back to render more nicely at
those zoom levels.  At the same time some other things were also fixed up.
The same process needs to be done for zoom levels 14 through 17.
