that help. a lot!
I tried it in so many ways to combine gemframebuffer, glsl and textures, 
but could not figure it out.
so this is great!
although it is not clear to me, why it has to be in that order? gemhead 
- glsl - gemframebuffer - texture - rectangle/...
anyway, there lies huge potential in this!
thanks for posting.
