I understand the necessity/convenience of internally choosing one alpha format
over the other. However, I'm curious how this would impact saving to image
formats that only support one alpha format (e.g. premultiplied alpha is
explicitly not part of the PNG spec[1]). Granted, I could be missing something
and it's not a huge issue, but I figured it'd be worth asking.
