[Rev 01] RFR: 8243505: SRC_OVER alpha composite mode doesn't render correctly

[Kevin Rushforth]

> This fixed a bug where blending won't be used for SRC_OVER alpha composite mode in cases where there is a non-zero
> alpha in the source, but the extra alpha in the alpha composite is 1.
> The evaluation is in the JBS issue. I'll file a follow-up issue for a couple things I discovered while looking into
> this.
