Matt,
I'm afraid there isn't that much rhyme or reason to worldfile handling in
GDAL. It is basically added on a driver by driver basis, and no always
consistently. Most WORLDFILE parameter checks should be using
CSLFetchBoolean() which would honour ON, TRUE, 1, or YES as valid positive
values. I checked, and it seems the PNG driver should honour them all.
Best regards,
