Reads or writes the blend factor you apply to the color values of the incoming fragment.

The following source and destination color components are described as (Rs, Gs, Bs, As) for source components and (Rd, Gd, Bd, Ad) for destination components.

The components have integer values between 0 and (kR, kG, kB, kA), where kR=2mR 1, kG=2mG 1, kB=2mB 1, and kA=2mA 1.

(mR, mG, mB, mA) is the number of bitplanes for each red, green, blue, and alpha value.
