There are two possibilities for the interpretation of clearing a canvas.
One is that everything is removed from the canvas, the other one is that
the canvas is completly filled with a specific colour. The first alternative
implies that the objects drawn are stored somewhere so that you can
identify them for the removal.
However, the idea of the DynamicLineArt object is that it provides a very
simple approach for drawing two-dimensional graphics. The drawn objects are not
stored.
So, to answer your question: every pixel of the canvas (aka BoundingBox) is
redrawn with the OriginalRefFillColour.
