set_snapping

Turn the board's two kinds of coordinate snapping on or off. to_curve makes the cursor ride a plotted curve and lock onto crossings, so the readout gives a point that is genuinely on the graph; to_grid rounds a free reading to the nearest grid line. The student has the "Snap to curve" checkbox for the first of these, so read `snapping` back before explaining a coordinate — a reading of exactly (5, 5) means something different when snapping is on than when it is off. Turn to_curve off when you want the student to read a raw position, and on when you are pointing at an intersection.
