[MaterialShapeDrawable] Custom shadows with Paint's `setShadowLayer`

In my project i use Paint.setShadowLayer(float radius, float dx, float dy, @ColorInt int shadowColor) inside my custom Drawable, for custom shadows. I want to switch to MaterialShapeDrawable, but i can't configure MaterialShapeDrawable's Paint with this custom values.

I think it would be great, if there will be function `MaterialShapeDrawable.setPaintShadowLayer(float radius, float dx, float dy, @ColorInt int shadowColor)' which i can use for custom shadow configuration.

Maybe there is a possibility to select by brute force applicable values with shadowCompatOffset/shadowCompatRotation/shadowCompatRadius for my case, but in this case MaterialShapeDrawable will use bitmap for shadows.

Inizia individuando MaterialShapeDrawable e verificando come vengono applicati il relativo Paint e i valori shadowCompatOffset, shadowCompatRotation e shadowCompatRadius. Confronta questo comportamento con Paint.setShadowLayer e determina il comportamento previsto dell’API e del rendering. L’attività è completata quando è possibile configurare raggio, offset e colore personalizzati senza dipendere da ombre bitmap, con una copertura del comportamento risultante.
