[REBOL] Re: Graph Drawing & /View Performance

Hi Romano and all,
>From my experience:
-use "show f" on each face when you need refresh small parts of window but
don't use it when you need show lot of small faces
-using one "show f" for whole window is better when you are controling more
faces in the window at the same time...then you rather use 'redraw function
in each small face instead of 'enagage
you can see the performance difference in following examples:
http://www.rebol.cz/~cyphre/draw-tutor-2orig.r - this script uses method of
refreshing each object face separately
http://www.rebol.cz/~cyphre/draw-tutor-2.r - this script uses method of one
global 'show of the whole window area
regards,
Cyphre
