Add feature to dim rows as we move further away from mid row

[commandiron]

hey, ı try your suggestion instead of fixed 0.2f. I am not sure it feels good because you can mostly see 2 row of them while rotating. I'll think about it or I'm open to new suggestions

As the dim rows move away, their rotation and opacity change. I will review the size as well next release.

Opacity is fixed at 0.2f even if rows move further away.
You can replace it by 0.2f / (distanceToIndexSnap / singleViewPortHeight)
