I did some work on brush rotation a while ago, https://github.com/jacksonmj/The-Powder-Toy/tree/experimental-brushrotate

I got particle creation and render_cursor working, but wasn't happy with the user interface for setting brush angle. Interface is one of the messiest parts of powder toy, so I eventually got distracted and forgot about it.
