Toonz Stroke to Synfig Outline (Bezier to Hermite)

Here I would I like add the starting point of the whole conversion-to-stroke process:

morevnaproject/opentoonz/blob/ac3067fb0cdbdcbc4f7fca959cf0d6c212586fb4/toonz/sources/toonzlib/tcenterlinetostrokes.cpp#L763


return result;
}


//--------------------------------------------------------------------------


// Converts each forward or single Sequence of the image in its corresponding
// TStroke. Output is a vector<TStroke*>* whose ownership belongs to the user.
// This allow sorts on the TStroke vector *before* adding any stroke to the
// output TVectorImage.
// std::vector<TStroke*>* conversionToStrokes(void)
void conversionToStrokes(std::vector<TStroke *> &strokes,
                       VectorizerCoreGlobals &g) {
SequenceList &singleSequences           = g.singleSequences;
JointSequenceGraphList &organizedGraphs = g.organizedGraphs;
double penalty                          = g.currConfig->m_penalty;


unsigned int i, j, k;


// Convert single sequences
for (i = 0; i < singleSequences.size(); ++i) {
  if (singleSequences[i].m_head == singleSequences[i].m_tail) {

This is what I came across https://math.stackexchange.com/a/3046666 as a conversion from cubic bezier to hermite

This is what actually should work - https://github.com/synfig/synfig/issues/851#issuecomment-508565338
