IMPORTANT: the strategy moved to the configuration, high level we want something in this spirit: The look up strategy of an icon is the following one: 1. Check in the server classpath in icons/override/${icon}_icon32.png (optionally icons/override/${icon}.svg if in the preferences), 2. Check in the family classloader the following names ${icon}_icon32.png, icons/${icon}_icon32.png, ... 3. Check in the server classloader the following names ${icon}_icon32.png, icons/${icon}_icon32.png, ... This enable to 1. override properly the icons (1), 2. provide them in the family (2) and 3. fallback on built-in icons if needed (3).

Parameters:

container - the component family container.

icon - the icon to look up.

Returns:

the icon if found.
