did some experiments tracing #ExternalRay in #InflectorGadget Julia morphing.
the #ExternalAngle (expressed as binary expansion) of the rays of the inflection nodes in the #JuliaSet have unchanging periodic part corresponding to the starting minibrot, while the length of the preperiodic part increases linearly with each morph (e.g. adding a constant number of bits each time), zoom depth is constant, but the stretching dynamics sometimes need precision to be increased.
compare with #MandelbrotSet morphs by deep zooming, where the length of the periodic part (and thus iteration count) increases exponentially with each morph (e.g. doubling each time), and zoom depth goes up typically by 150% (requiring 150% higher precision).
