mapPoint method

({double x, double y}) mapPoint(MapDirection direction, { required double x, required double y, })

Map a point between viewport coordinates and video frame coordinates. Returns the mapped coordinates as a record ({double x, double y}). https://github.com/wang-bin/mdk-sdk/wiki/Player-APIs#void-mappointmapdirection-dir-float-x-float-y-float-z--nullptr-void-vo_opaque--nullptr
