My friend suggested me that general native matrice operations could be used for many computational stuff, but I am no math folk, so I don't know if it would help.
However - here's link Rebol is talking about upcoming effect pipeline: http://www.escribe.com/internet/rebol/m15951.html taken directly from Holger's description: - Added "func" effect. This allows you to call a REBOL function from within the effect pipeline, manipulate the current image (including its alpha information) and pass an image back to the effect pipeline. Is that what you are asking for? Or do you mean operations upon image datatype directly? Now another question popped in my mind - are Core and Command users left behind? What do I mean? Core and Command both know image datatype. But they don't know of face composition. How can we work with images using Core and Command? Hmm, shouldn't datatype manipulation functionalities be part of the kernel of the system?
