Joachim:

Could you explain this using small words :)  I don't have experience with
combiners, so a brief explanation would be helpful in understanding what it
does and what the limitation of this implementation are.

one register combiner is used.

Well I was distracted by the sentence
"where CNx is the x component of the Nth color operand in the
combine operation." But after your explanation I understand what's
actually meant

Thanks
