Update to plotting of event nodes:
Distance is now 1.5, scaling and cutouts are possible
(with some lack of precision).
Still missing: y axis labeling (no numbers, but node names).

Add a flag 'alle' (all event nodes) to the plot command (and maybe others).
All event nodes with length greater than 1 are translated to vectors
with a common scale (named step) and are assembled in a new plot
named 'digital'. They may be plotted or otherwise used in a
.control section.

The re-painting due to mouse-click under MS Windows is caused by line 561
of windisp.c. Upon left mouse button up the plot recangle is invalidated,
and a WM_PAINT message is generated (same on line 614 for right mouse
button up). If not re-pained, artifacts may be left on the canvas after
collecting coordinate data.
Shifting the command InvalidateRect to a place where it becomes active
only after the mouse has been moved, does the trick. Simple clicking
(right or left) will not cause a re-paint any more.
