Remarks
Configures the ambient & spot shadow alphas. This is the alpha used when the shadow has max alpha, and ramps down from the values provided to zero.
These values are typically provided by the current theme, see android.R.attr#spotShadowAlpha
and android.R.attr#ambientShadowAlpha
.
This must be set at least once along with #setLightSourceGeometry(float, float, float, float)
before shadows will work.
