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
