  • Soften shadows even more; fix shadow alpha. This change uses globalAlpha to make the shadow transparent rather than using rgba on shadowColor, which is not supported as of today.
  • Add a test for transparent occluder.

This requires a golden update: flutter/goldens#90

Fixes flutter/flutter#55786
Fixes flutter/gallery#118

Is a linear reduction the best option? Would it make sense for already softer-alpha shadows to reduce by an even smaller factor than 0.3?

Happy to change it if there's a concrete use-case. This seems to work fine for the gallery (at least all the places where I could find shadows).

Let's chat about a different way to adjust alpha. This seems to fix the immediate issue. We can improve it further in subsequent PRs.
