    *  IslandDraw is not a full fledged postscript interpreter but

Somebody from Island Graphics `ought to be' replying to this.
However, to the best of my out of date knowledge, IslandDraw
does NOT contain a PostScript Interpreter.  IslandDraw's
predecessor, SunDraw, could read a limited subset of
ENCAPSULATED POSTSCRIPT -- that is PostScript containing a
preview image.  It is the preview image section that IslandDraw
(SunDraw) would display, with the result that every user then
leapt to the monstrous non-sequitor that IslandDraw contains a
PostScript Interpreter.

    *  Unfortunately it seems the Mathematica-generated postscript
    *  file is very complex (specially the MathScale thing). Thus,
    *  short of stripping off almost everything in the file, is
    *  there anything I can do to modify the postscript file to
    *  something more conforming (and readable by IslandDraw) ?

You didn't say WHY IslandDraw could not `read'
Mathematica-generated PostScript.  Does IslandDraw display any
messages?  Does it simply die?  Does it reject the
Mathematica-generated PostScript?   SunDraw used to expect to
import EPSF 1.2 format.  I don't know if IslandDraw was upgraded
to import EPSF 2.0 format.  What does the IslandDraw manual say
about EPSF?  In general, if a program designed to read
Encapsulated PostScript can't, the Encapsulated PostScript is
bogus in some way.  Remember that there are two versions of
Encapsulated PostScript for every application programmer
generating the stuff.
