[PD] [Gem] fork pixes

[Peter P.]

Thank you Jack,

Indeed! I was aware of the GL separate object but didn't know that I had
to use the same approach for pixes. Somehow I feel this could be
mentioned in some GEM docs (but where?).
Thank you for your kind reply! I am curious how it could be done using
shaders, but am quite happy the way things are working now!

all the best, Peter
