Hi Denis,
Reading the code, does this mean that in a stroke, the first width is
the pen width (what you call the nominal value)? and then the second
value is the width of the first segment, the third of the second
segment, etc. etc.?
<stroke tool="pen" color="red" width="1.41 0.51 0.53 0.34 0.07">
196.57 423.87 196.80 423.54 196.97 423.32 197.40 423.54 197.60 423.82
</stroke>
