    ST-80 Compatibility mimicri for Icon.

    Implements the #constantNamed: message which is used by some ST-80 PD

    classes and returns corresponding ST/X icons.

    If you like the original ST-80 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).

    You can grab those icons from manchester or from the PrimeTime Freeware CD.

    A copy of the PTF-CD is also in goodies/bitmaps/st80bitmaps.

    Then, change the replacementName method to return an empty array.

    Caveat:

	masks are not yet implemented
