I'd like to add these large PNG graphics to my suite for performance  
testing.  If they're available, please let me know where I can fetch  
them from.  Thanks.

Thank you for the patch.  I will experiment with it.  I now have both  
PowerPC and Intel Macs so I can do some comparisons.

5% (if that is what you meant) is not much of a gain.  However it is  
just enough that the patch is worth considering.  Of course,  
modifying the core inflate code must be done with great care.
