oupse I've mixed [pix_threshold] and [pix_alpha]

it's about pix_alpha rather but I think you've understood,

indeed I'd like the particle reveals background image

the idea is about snaping the particle system over a black rectangle (the mask)

and then turning the white pixels to alpha for revelating the (purple) rectangle
that should be rendered first

i've attached again the same patch but with [gemhead 5] instead of [gemhead 0]
