Purpose of fadeLayer ?

[namanhams]

I removed fadeLayer property of FBShimmeringMaskLayer, and commented out all the code related to this property. Everything still works fine. So my questions :

1. What's the purpose of fadeLayer ?
2. Since FBShimmeringMaskLayer is used as a mask layer, only alpha channel will be used. And fadeLayer is a sublayer of it, how does it affect anything here ? I tried to change the background colour of fadeLayer to various colours with various alpha values, but it doesn't have any effect.

If you look at the .gif in the README, the fadeLayer implements the fade-in effect after the shimmering stops, timed to match the beat of the shimmer. If you take it out, it will just snap back to full opacity when the shimmering finishes.

Thanks @grpaul , i agree. But seems that changing the shimmeringBeginFadeDuration or shimmeringEndFadeDuration doesn't have any effect on the fading animation. Do you know why ?

Thanks for catching it! Looks like the fade out duration wasn't being respected. 0959467 should fix that.

@grpaul : I think you forgot to set the animation duration.

Oops. Fixed in 80174f9 (along with a minor issue applying the shimmering width).
