Drop shadow effect
Add a drop shadow around what is visible on the object or layer.

Parameters
- Distance and Rotation set how far the shadow is offset and in which direction (the rotation is an angle in degrees).
- Blur softens the edges of the shadow, and Quality controls how smooth that blur looks (higher values look better but cost more performance).
- Color and Alpha set the tint and opacity of the shadow.
- Enable Shadow only to hide the original image and keep only the shadow, which is useful to build a separate object acting as a cast shadow.
