well, you don't have to display your image.


will do a lot of work without displaying anything (as no [rectangle] 
gets drawn anywhere in the gemchain); nevertheless all the pixel-data 
(and openGL-stuff) is really executed, so it is available for whatever 
you want, e.g. [pix_record] or [pix_write]
