export const invertMatrix = (point: Point, matrix: Matrix, tag: 0 | 1 = 1): Point => {
  if (!matrix) { 
    matrix = mat3.create();

  const inversedMatrix = mat3.invert([], matrix)
  const vector = [ point.x, point.y, tag ]
  vec3.transformMat3(vector, vector, inversedMatrix)

  return {
    x: vector[0],
    y: vector[1],
  };
