+ When you render tiles with certain types of symbols, some map
+ servers may render artifacts at tile edges that make symbology not
+ look continuous. Look at the state abbreviations, open the layer
+ switcher and change to the layer with a 15 pixel gutter to see how
+ the symbology looks different (the server in this example doesn't
+ render such artifacts, so the client-side gutter won't make things
+ look nicer).
