From Konstantin Matveyev, submitted by Valery Bickov:

"There is error in WoW shader, you can see it by this simple example:
osgviewer cessna.osg --wowvx-42 --clear-color 0,0,0

Clear color may be choosed any with at least one component equals to 0
or 1. In my case I see weird blinking between normal image and image
with depth map at right side on the screen."
