Description:

A multiImage is an image which is drawn by drawing multiple images on top of each other.
Typically, they are used to overlay additional information,
for example a stop-icon or a link-arrow over a fileType icon.

try: 
    MIMETypeIconLibrary iconForFile:'/foo/bar/baz.c' asFilename

caveat:
    instances provide enough protocol to be shown as icon, label, etc.
    (i.e. provide a replacement for images and forms).
    However, not all tools are prepared for them not having mask, bits etc.
    Especially, the ImageEditor gets a bit confused and may fall into a debugger,
    if trying to edit one of my instances.
