Bevel Layer Style
The bevel layer style adds a bevel or relief effect to a layer.
The Depth parameter controls how much the inner areas will be raised above the background.
Azimuth controls the light direction (top/right/bottom/left).
Elevation controls the distance of the light source from the image.
The bevel layer style calculates a highlight and a shadow pass, and blends them with the layer according to the Opacity, Mode and Color parameters.
