Fix vcl alpha blending n#714787
The way alpha compositing took place in vcl's alpha vdev was subtly
wrong - it was supposed to implement porter-duff 'over', but didn't.
This is now fixed also for cases where the source surface contains
alpha, and needs to blend correctly into fully-transparent
background.
