--- Comment #8 from Ken Phillis Jr kphillisjr@gmail.com 2010-06-12 20:58:38 --- I went ahead and checked to see what the hex value was that was getting stuck into the parameter, and here's what i found... 0x7fa02001 This signals a quiet Nan signal according to IEEE 754 Representation. so I think the best choice is to return on this one and not change the renderer values.
