Maybe, although I've been doing image processing tasks for
years without ever yet finding myself needing polygon clipping.
I don't know if that is an indictment of my image processing
abilities or if it indicates that maybe polygon clipping is
not as mainstream as an FFT.

In any case, I suppose I can understand "surprise" or
"disappointment". But "annoyance" annoys me. Or, at
least it did this morning. :-)

Cheers,

David
