lightningterror 3b691da8d1 GS-hw: Implement alternative hw blending for Cs*Ad, Cs*Ad + Cd, Cd - Cs*Ad. 
Alpha destination value is wrong so let us try to compensate.

Multiply Cs by (255/128) in shader.
Will work best if Cs is 0.5 or less,  if it's higher than 0.5 then the closer to 1 the less accurate it gets.

Ofc it is best to use sw blending but it will help if sw blending is not present/selected for specific draw, will help d3d11 quite more.

lightningterror 4ab9d1a493 GS-hw: Implement alternative hw blending for Cd*As, Cd*F. 
Do hw blend for Cd*As, Cd*F, expand the clear color blend method as it is almost the same.

Most helpful for dx11 ofc, for gl/vulkan will help with rendering on lower
levels of blending without needing a barrier.

lightningterror 3c92054a6e GS-hw: Move PABE shader bit to the top of sw blending. 
Early return when there is no sw blending, no need to run the blend code.
Optimization.

lightningterror 6a431daffc GS-hw: Extend Blend mix to work when alpha is higher than 1. 
Clamp the alpha(As/Af) to 1 in the shader, it is already clamped to 1 in hw blend unit.
It should allow to better render the effects, still not fully accurate but it's closer to what we want.
Hopefully it helps D3D11 more.
