I dispute the above assertion. As long as you keep the a couple of lines
intact (ie: buffered), and work downwards.... I don't see any reason why one
copy of the grid won't work. In fact, I'm sure it will. Grab a line, check
above.. (using the buffered line), check below, etc.... when you've
calculated your new line... write the buffered line to the grid, copy the
new line to the buffer, and proceed to do the next line. The algorithm
would never see the 'new' grid, it would always be working with the 'old'
one.
Cheers
