423 * Propagate the alpha value through the pipeline.
425 * As the UDS has restricted scaling capabilities when the alpha component needs
426 * to be scaled, we disable alpha scaling when the UDS input has a fixed alpha
427 * value. The UDS then outputs a fixed alpha value which needs to be programmed
428 * from the input RPF alpha.

438 * the output alpha value is thus always equal to 255.
