Retroactively edit a Voronoi pattern

[caroliner99]

I'd love to be able to go back and edit a Voronoi pattern. Integration into the feature timeline would be great, so that I could go back and change the number of cells or space between cells in the pattern without having to make a whole new pattern and delete the old one.

@caroliner99 Yes, that would be a nice addition. It's something I've considered in a rewrite I've been planning. I'll star it in my todo list for the update. Thanks for the suggestion.
