   It's not a technique, but a basic behavior of the program. See my 
last post on p.unofficial.patches, with subject "To clip or not to 
clip...". There are also many discussions about this "hot" topic on 
these newsgroups: just search for "clipping"...

   I didn't test it, sorry: I only wanted to get ride of the grainy 
results. But I think the speed should be similar with both methods.
