The BCC Light Sweep filter creates a linear beam of light that sweeps
across your image. The filter is physically modeled after a light that is
infinitely far away. The light is infinitely wide in one direction, and falls
off in the other. Light Sweep also has some very useful edge detection and
edge lighting features.
The built in PixelChooser, with integrated mocha planar tracking allows for
greater control over which areas of the image the filter should affect.
