"""
Bandlimited versions of scipy.signal.waveforms.

Intent is mathematical perfection over performance;
these use additive synthesis, so they are slow, but exact.

Less ideal methods using BLIT:
Sawtooth can be made by integrating BLIT minus a DC value to prevent integrator wandering off
Square can be made by integrating bipolar BLIT
