Morpho Trace Menu Redraw Options

Skandha Morpho currently implements a rather simple-minded graphics-port management policy which at least has the virtue of being predictable and controllable.

The intended usage pattern is to select "Redraw Image" to erase all contours displayed, whenever the screen grows too cluttered, and then use the other redraw options to display as much contour context as you wish.

In essence, Skandha Morpho draws something only if and when specifically asked to, and no more that specifically asked:

When you select "Next Frame" or "Prev Frame", it draws only the image for that frame.

If you select "Redraw Image", it draws only the image for the current frame.

If you select "Redraw Contour", it draws only the contour indicated by the current "Tube:" setting.

If you select "Redraw This Section", it redraws all the contours measured for this frame, but does not redraw the image itself.

If you select "Redraw Prev Section", it redraws all the contours measured for the previous frame, but does not redraw the image itself; they will be super-imposed on the image of the current frame.

If you select "Redraw Next Section", it similarly redraws (only) all the contours measured for the next frame.
