[OSM-talk] Mapnik boundaries

Did someone break the boundary rendering on the Mapnik layers?

It looks like all boundary relations on a given way are now rendering, 
and that means that if two or more relations for different admin_levels 
are on one way, different kinds of borders are rendered on top of each 

I guess this may have to do with someone thinking a relation with 
type=boundary should be treated the same as type=multipolygon (there's 
a proposal for that hanging around somewhere to tag boundaries with 
multipolygon relations, not a good idea IMHO, just because of this bad 
kind of rendering), but that's only guessing since I didn't look at the 
code, I just see the same wrong kind of rendering happening now to 
boundaries tagged with a boundary relation as those tagged with 
a "boundary multipolygon" relation.

So, please fix this as current boundaries look pretty bad now. Given the 
current maritime boundaries getting voted on it's a good time to make a 
*proper* handler for boundary relations.
