I filed:


a few weeks ago on this general point and I thought my patch had corrected
the bulk of the issue but I did not dig deeply.  It did fix up the problem
I encountered.  Perhaps you could add additional notes on what isn't working
for you in that ticket?  The change I made was primarily altering the new
built-in jpeg and png writers to use msIO functions.
