But isn't each stroke with a tool a separate GimpPaintCore object? In
the warp tool's case, I would like sequential strokes to have access
to the same original image, the one before the first stroke. Is there
any existing infrastructure to do this, or would the warp tool code
need to manage such bookkeeping itself?
