Improve options for handling source images with packed alpha channel
As it stands right now, there are images I'm working with that have packed alpha channels that I have to edit to remove or split the alpha channel. Where the alpha channel value is 0, it generates new RGB data interpolated from areas where alpha is not 0, rather than just falling back on the actual contents of the RGB channels, which is what I'd like it to do. I'm supposing this would be done ideally with adding a 4th alpha mode so that the functionality of the existing methods stay the same for compatibility reasons.

To clarify, I'm referring to
Alpha: SuppressandAlpha: Removemodes, neither of which handle alpha values of 0 in my desired manner.
