Ah, that's intriguing... actually, I think DEVICE,
BYPASS_TRANSLATION=1 is what I want. I had DEVICE,
BYPASS_TRANSLATION=0 in a startup file that, indeed, I got from a
friend (who probably didn't have my best interests in mind). Almost
everything else in that startup file makes sense to me, but I had no
idea about this one. And bingo! That seems to be the trick. By
setting the bypass to 1 I got a png file that actually looks right! I
think that might have solved the problem....

Thanks so much! Phew!
