CompositeOperator

Is the if-clause in ImageCairo.cpp still necessary?

    if (op == CompositeSourceOver && !frameHasAlphaAtIndex(m_currentFrame))
         context->setCompositeOperation(CompositeCopy);
     else
        context->setCompositeOperation(op);

Other implementations don't change the CompositeOperator. And in this case it
causes the black background. Why is it there?
