			This is fairly straightforward, other than the fact that the nomenclature gets a bit awkward with the aForce parameter on the ForcePaint methods. I'm not sure which direction to go with this - "aForce" seems a fairly intuitive name for what we want, and I'm kind of inclined to say the existing ForcePaint mechanic should be renamed to something like PaintWithInterrupt, or PaintWithPriority.
