rowbytes check correction The old code incorrectly calculated the output rowbytes when the application decreased either the number of channels or the bit depth (or both) in a user transform. This was safe; libpng overallocated buffer space (potentially by quite a lot; up to 4 times the amount required) but, from 1.5.4 on, resulted in a png_error.
