Light Rays
Uses the zoom blur rather than a gaussian blur to distribute the glow eect. The resulting eect
is that of light rays shining through an object from a specied point.
This lter causes rasterization in 3D groups. For more information on rasterization, see Groups
and rasterization on page 1045.
