@tetris The source has no other relevant info for you. But pixelation worked like this: A colored background layer is covered by a differently colored front layer - both full size.
Now you take f.i. a text layer with just one word (say "HELLO"), set its opacity to zero.
Then start a loop copying the text layer randomly speading copies all over your layer.
If the text was intransparent you would see the screen quickly filling up with hellos, simply overlaying your front color with a cloud of hellos.
However with text fully or near transparent pixelation occurred by the back colored layer breaking through the front colored layer anywhere at least nine text objects overlaid each other fully or in parts.

Here's a visualization i did in a newer Photoshop just now, using the word HELLO. Front color Black, back color white, the pixeled overlays are clearly visible, but should be plain white in fact.

@jrp That is incredibly interesting! So it's mostly an artefact on the Max number of overlapping opacities, right? I wonder if SVG has such a limitation... I may have to do some experiments in different browsers
