...sure, that's not the correct ordering:  in general you can think of 
[pix_film] and [pix_texture] as being book-ends, so you use the other 
pix_* objects in between...[pix_film] is producing one frame from a 
movie:  a pointer to this frame is then handed between intervening 
[pix_*] objects, which can then perform operations on/with it...this 
occurs until hitting [pix_texture], which takes the pointer and uploads 
it's associated data to the graphics card...you can still play with the 
data at this point, but you need to use vertex or fragment programs, 
and this is pretty experimental in GEM atm (ie. no examples)
