    Compatibility mimicri for Icon.
    Implements the #constantNamed: message which is used by some PD
    classes and returns corresponding ST/X icons.
    If you like the original icons, install the xbm files in the bitmap
    directory under a name foo.xbm, where foo corresponds to the icons
    name symbol (i.e. for Icon constantNamed:#foo, a 'foo.xbm' file is required).
