More frills. I've added vertical offset and vertical scaling
factoring options to the horizontal ones for the 'saved' files on
the ABC player on my website, and (optionally) a display of the %
time that the tune spends on each note. Octaves are ignored, but rests
included. Grace notes are ignored, after their time is restored to the
notes they borrowed it from.  
 
What's interesting is to compare a tune and its gigga version. 
[e.g., 4/4 "St. Patrick's Day" in James Oswald's 'Caledonian
Pocket Companion' with the 6/8 version following it (T025A and B
in file T1.HTM on my website)]. Multiply the x scale of the
6/8 version by 4/3 to match the time scales and see how very
similar the tunes are. 

Even better, offset the vertical so they are on top of each
other. The last tune plotted will be continuous in color #2, but
the first will show only the differences in the other color, #1,
because all that's the same gets overwritten by color #2.

I think my plot display works now. I had troubles from the fact 
that the display in the compiled version is a bit different
from that in the developmental working version, and I found that
it lost essential information to the top left of the plot screen.
