Thanks again for the positivity- I haven't forgotten about this, just trying to find time in about everything else I have to find the time to do...
Anyway, bucket fill soon, I promise. I've got an algorithm worked out. And I also made a very minor bug fix for Chrome, where the cursor was defaulting to the text cursor whenever you tried to paint.
Anyway, once I make my fortune and don't need to work, and my kids learn to change their own nappies / use the toilet etc, I'll totally work on this full time.
