This should fix https://github.com/azchohfi/LottieUWP/issues/4 and the progress bar sample in https://github.com/azchohfi/LottieUWP/issues/35

After a lot of going in circles, this one line change fixed the mask errors I was having. Of all the blend docs I read this one from QT gave a clear reason why SourceOver should be used. https://doc.qt.io/archives/qq/qq17-compositionmodes.html
