[GPU] Treat color and alpha sources as two separate RGBA values
...
Previously we fetched the RGB channels of the color source and the alpha channel of the alpha source
and combined these into a single RGBA source value that the source operands are applied to.
This is incorrect. The correct behavior is to fetch the full RGBA color for both the color and alpha
sources and to apply the color operand to the color source and the alpha operand to the alpha source,
i.e. using the *alpha* source R-channel when the alpha operand is "One minus source red".
Only after that we combine both sources into a single RGBA color.

there are other GPU registers between the first four combiners and the last two.
