#X text 30 3 Making waveforms with corners using parabolic waves;
#X text 14 499 Here we combine three parabolic waves (in the same way
as \, two patches ago \, we combined sawtooth waves). The parabolic
wave is obtained from the sawtooth wave (assuming it runs from -0.5
to 0.5) by the formula: y=x*x/2 - 1/12. This is normalized so that
the corner has a slope change of minus one unit per cycle \, and adjusted
to remove any DC component.;
#X text 12 593 In general \, the segments of the result will be curved
\, but if the three magnitudes sum algebraicly to zero \, the segments
will be linear.;
