[Insight-developers] clearing the output image in a filter

Good suggestion.... I don't think a straight implementation of FillBuffer 
would work, because it wouldn't destroy the existing objects on the list. 
But I was able to copy the FillBuffer() code and modify it slightly to call 
EmptyList() on each pixel. This seems to have solved the crashing problem.

My original approach was to create an iterator, and use this iterator to 
access each pixel in the image. Any idea why the straightforward buffer 
increment design works and the iterator didn't?

Thanks for the help,
