PancakeView using BackgroundGradientStops instead of BoxView

[aimore]

Just found this(another from many) cool library and I was wondering how the animation using
PancakeView BackgroundGradientStops would look like, I think it would be really close to shimmering effect used by facebook for example without actually using any binding.

I used the PancakeView to create something similar https://player.vimeo.com/video/402107393#t=35s

This is not an issue, just a suggestion.

Thanks for the great work!
