 True to the theme of "premature optimization is evil", the legend
 component currently re-reads all associated Layer Definitions on disk to
 re-read all the matching icons and scale ranges every time it is
 refreshed.

 This is obviously an excessive amount of unnecessary I/O (as each
 GetResource call hits the disk for the content) and such information
 should be cached locally.
