Blends source into target
with respect to the opacity of the source image (as stored in the alpha channel).
This variant is faster thanalphaBlendRGBA,
but leads to a wrong alpha-channel value in the target.
Useful because of the performance advantage in cases where the resulting
alpha does not matter.
