Horia Iosif Olaru c26db357b5 Bug 952051 - Change the GetOperator call in FlushGroup to take into account the mix-blend-mode operator for the group. r=roc
Create a new GetEffectiveOperator function that also takes into acount the mix-blend-mode operator for basic layers. Replace logic that chooses between the effective mix blend mode and the operator returned by GetOperator, with calls to this function.
