[ITK-dev] System PNG sCal issue

[Bradley Lowekamp]

Great! That is what I was looking for and why I kept thinking I have seen this issue around...

Not sure what the real issue is... maybe the png file in the test in invalid, and the lib png change the behavior for this case.... I just don't know yet.

I did determine that the spacing of the output put image for this system in 1, while the passing tests have 0.25. So this is the right problem... just need to figure out where the behavior is going wrong.
