Comment(by jng):

 The caching of layer icons has changed the behaviour somewhat. A layer
 that has multiple scale ranges will always have the icon for the first
 scale range. Moving to a scale that's in a different scale range does not
 update this icon.

 Our Layer Metadata needs to cache icons for all applicable scale ranges
 and the node rendering needs to fetch the appropriate icon based on the
 current view scale.
