On the other hand, why couldn't I simply AC-couple the square output to the
integrator input?  This might cause a rounding of the triangle apices, but
I'm going to shape it into a sine anyway, so does it matter?  Of course,
this doesn't address the integrator offset, does it?

The other alternative is to use a lossy integrator...(thinking aloud)...?
