Comment 8 for bug 535806

Gabriel, we discussed MNG back in the days and found that it was not very well supported. Not by graphics program (creating/viewing) and not by libraries (most solution we found were quite hackish). Also, the reduction of the files to read would not be dramatic.

I suggest that you make a quick-n-dirty hack first and profile this if it really makes significant improvements in the loading of the graphics (cold harddrive cache will be important). I doubt it. And if this is the case, we need to roll a system of our own - I have an idea for that which would also give some other advantages - we could discuss this then.
