[PD] [Gem] Alpha: transparency only in one direction?

[Roman Haefeli]

sorry for my language.
i see that one can change the execution order dynamically, but this
doesn't help in the case when two rectangles cross each other (like an
'X'). then you have at the same time the first AND the second rendered
rectangle in front, but only one part is transparent.
