Let's try that again...

Yes it would, except for one thing: dvipng-1.6 would complain about an
unknown special. I inserted the string needed for detection of the
preview-latex <= 0.9.1 tightpage option, that is "!userdict" followed
by a string containing "7{currentfile......div", the extra brace is to
make TeX happy. The tightpage flag inside dvipng will be set twice, but
that is all that will happen. It is after all a PostScript comment.
This way, the compatibility code would not need extra code within
dvipng, and is situated in one place only, thus easy to remove. But
perhaps I should have documented this in the PostScript comment?
