This ROP decides if the previous pixel is inverted or not.
ROP output:
This ROP determines which pixel to select for the current mixer
output. ROP output:
This ROP value determines whether or not to do an alpha blend.
ROP output:
This ROP generates the key which is passed to the next layer mixer
and is used as KEY0 in those ROPs.
This ROP value determines which alpha is passed to the next mixer
stage. ROP output:
