I remembered the labelcache_map_edge_buffer a second after I hit send. I started with
with MapServer layer but ran into some problematic memory leaks that seem to be caused
by a weird combination of platform/python/mapserver/tilecache. The MapServer tile cache
layer sets that for you and wms does not. So, I'm re-populating the cache right now.
(BTW it would be useful to have an option to force re-rendering of tiles when seeding.)
Would be happy to write something up. Is there an example someplace?
