Description of Changes
Since we can't do
Cd*(Alpha + 1) - Cs*Alpha
in hw blend what we can do is adjust the Cs value that will be subtracted, this way we can get a better result in hw blend. Result is still wrong but less wrong than before.Rationale behind Changes
Accuracy.
Suggested Testing Steps
This is mostly for dx11/12. Vulkan, GL will only hit this path if barriers are disabled.
Makes dx hw blend suck less.
Test DX blending, list of games in the text file.
Result will still be wrong but less wrong.
