Hi,
Steve Passe:
|if hue or brightness are moved from posative to negative the update
|pushes them to max values
|
|if chromaU is greater than 141 it goes to the minimum
|if chromaV is greater than 101 it goes to the minimum
Yeah, that's another thing I found later this afternoon, but I thought it
could wait for 0.4. Here's the diff.
Randy
