Thankyou gentlemen.
I didn't realise that Antialiasing was an option in Povray.
Then - found it was ALSO an option in LSP-Addon.
Now that I've turned it off in both, I've got over my issue :-)
PS - I'm afraid using "alpha channeling" is a bit beyond my knowhow,
so I'll go with Travis' "newbie" idea.
ie turn off AA, then subtract pink in GIMP, then shrink with AA.
