Yes, that was quite a thorough explanation, thank you for that :). Took
me a while to read through all of your reply as well as look through the
accompanying code. I can definitely see that, yeah, this is quite a bit
more complicated that it appears at first glance. This will take a lot
more thought before tackling, and I am unsure if honestl it may be a bit
over my head as well, but I suppose I will see, haha.

Regardless, I did learn a lot, so thank you for taking the time to make
such a detailed reply!

If I do end up seeing something I can improve will definitely cook up
a patch and send it in, thanks again!
