Long Shadow Layer Style
The long shadow layer style adds a shadow effect which looks as if cast by a very low light source just above the image plane.
The area for which the effect will be generated can be enlarged using the Padding parameter.
How the shadow is blended with the background is controlled via Mode, Color and Opacity.
Angle specifies the direction of the shadow.
The shadow can be blurred using the Blur parameter.
The Distance parameter can be used to raise the layer above the background plane and add to an offset to the shadow.
