My first attempt at writing an AVISynth filter, so I hope I did it right.
This filter can correct the white balance of video that was filmed with a camera where the white balance was incorrectly set or didn't have an adjustment. Especially useful for home video filmed indoors on consumer camcorders, or filmed outdoors under overcast skies.
Has some features that result in more accurate white balance adjustment that attempting to use RGBAdjust() or ColorYUV().
