hey all,

I just plugged the same 3 channel, RGB image to both A & B inputs of a
Merge(A,B) node, set operation to multiply....(ie: image^2).

The image has both positive and negative values.... the result has both
positive and negative values?!

I feel like I've taken crazy pills!.. (I would expect all values to be
positive)..... What kind of "Nuke try and help me out, without me
asking..because I can't help myself" mathematics is going on here?
