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
