Using the M3 rotation and coordinates system simplify the computation of the chevrons along the curved toolbar. As a result the chevron morph are rendered on a vector canvas. So shape morph detection works out of the box, it simplifies again my code (mouveOver detection). One side note: I can't put a Form (the icon of the chevron) on the chevron because the vector canvas does not accept Form. Any idea? Happy New Year 2021 to all of you!
