Conversion is performed such that the quadratic splines keep the same end-curve tangents as the original cubics. The approach is iterative, increasing the number of segments for a spline until the error gets below a bound. Respective curves from multiple fonts will be converted at once to ensure that the resulting splines are interpolation-compatible.
