Sets chroma Key parameters for the green and blue color channels.

Key width is used exclusively in the chroma key pipeline stage following the Color Combiner (if enabled in othermodes)
<math>\mathrm{key\_alpha} = \mathrm{clamp}(-\mathrm{abs}(\mathrm{Combined}) + \mathrm{Width}, 0.0, 1.0)</math>
Key center and scale are Color Combiner inputs, the expectation is that the Color Combiner is configured to <math>(X - \mathrm{Center}) \cdot \mathrm{Scale}</math> when chroma keying, where <math>X</math> is any color source. If not chroma keying, these may be used as general-purpose Color Combiner inputs.
