i am not really sure about this (so that is why tom is in the explicite 
receivers' list of the thread tooo...)

[gem_pdp.out] would just emit normal pdp-packets, so i think these would 
be understood by older pdp objects too.
i am not completely sure, what would be the content of these packages: 
probably just the pixel-stuff (in case someone wants a Gem-pixel-source) 
and the knowledge, that there is a valid openGL-context right now (which 
would even allow to use (unthreaded) 3dp)

btw i guess this would also allow the usage of pdp on windows, as the 
only non-portable things are (i think) input and output (which would be 
handled by Gem)

so this means, you are hacking GemPixUtils ? good!
