Yes, mime-surface seems like a natural fit. There is at least one  
problem with it as-is, though: Firefox loads images as they stream in  
on the wire; right now, it looks like mime-surface would require me to  
repeatedly remove and re-add the mime data to update it.

Ideally, I'd be able to call a mime-surface function after receiving  
data from the network that appends data to the mime-data, then  
continues the decoding process. We also sometimes know the size of  
images (and sometimes don't) when we're loading them, so we might or  
might not provide that information to Cairo right away.
