Notes:
- Icon Cache provides fast mapping of icon name to icon; when encountering
an icon name for the first time, the icon is loaded in using the facilities
of the Icon Source icon loader.
- Icon Source icon loader can be replaced with subclassed icon loader for
additional file formats supported (outside of what FOX provides).
- Icons loaded are not realized (created). This is up to the user to do;
rationale: not all applications need icons rendered for drawing purposes.
- An icon search-path determines which directories are to be searched for
the provided icon name.
- Since loading an icon may fail, don't map the name till we've successfully
obtained the icon.
