(Get the code!)
Hi Joe, thanks for the patch.
As far as I am aware, libpng doesn't provide any backward compatibility guarantee. The code works with 1.2, but, e.g., for 1.5 we need the change you propose in the other bug. There is no guarantee that the code will continue to work with libpng > 1.5 without further changes.
Therefore, depending on libpng >= 1.2 is not reliable enough; we need to explicitly depend on tested libpng versions (1.2 or 1.5 or any other tested version).
