hi, jack !

thanks for your suggestion.

this "sort of" works, meaning that with one [gemframebuffer] this method 
does what you say.

if i am using more than one glsl shader in a row, each with a 
gemframebuffer, it doesn't work anymore.

anyway, my strange "[pix_image] after [pix_film]" method still does what 
i want so i will stick with that for the moment.

best

oliver
