[Image-SIG] ImageFile._ParserFile

[Alexey Borzenkov]

Hi all,

I've been looking at ImageFile._ParserFile (used by ImageFile.Parser),
and suddenly thought that all it does is reimplement reading part of
StringIO. Why is it needed? Of course using StringIO.StringIO wouldn't
make much sense in terms of performance/etc, but cStringIO.StringIO
(with the usual try/except) might make sense. What do you think?
