Title: Fixed the ignoring of the alpha channel in WinRT (not ideal)

Not ideal, because it hardcodes `Premultiplied`, when the image format's alpha could potentially be `Straight`. However, this is still better than `Ignore` as it was before. It was because `decoder.BitmapAlphaMode` would return Ignore since Microsoft just sets it to Ignore regardless of format.
