However, this would leave unaddressed a long-standing issue with `ApplicationImageUtils.createLauncherIconResource()` function that requires the main launcher to calculate an icon resource for an additional launcher. At the packaging phase, any `Launcher` instance should be self-sufficient. Fixing `ApplicationImageUtils.createLauncherIconResource()` required adding a new interface `ResourceDirLauncherIcon` to the model and changing the semantics of the `DefaultLauncherIcon` interface.

The function is supposed to calculate a description, shortcuts, an icon, and any future launcher property. For now, it is used to calculate the launcher icon.
