OMG, thank you so much Subbu, that did it!   :-D

The xprop command did already return that exact output, but it wasn't until
adding that line you said to my .desktop file that it worked.

99%, anyway.  I'd hoped I'd be able to have a .desktop file for a specific
image (so it can have its own icon, instead of the Squeak icon).

    # standard Squeak icon for launching any image
    Exec=/usr/local/bin/spur %f

the other, for MyApp,

    # for launching MyApp's image.
    Exec=/path/for/apps/vm/squeak.sh /path/for/apps/image/app.image

I put both of the above into separate .desktop files at
~/.local/share/applications.  After an afternoon of tinkering, what I found
was a little strange -- for the icon, Ubuntu 18.04 seems to use whichever
desktop file was launched first.  However, even though it gets the icon
wrong, it at least uses the right Exec= vm specification.   I tried
changing the StartupWMClass on one of them, but it didn't work.  But, I can
at least work again..  :)
