1. simply using Transform Class.

class A {
  transform = new Transform()
}

const a = new A()

a.translate
a.rotate

2. using TransformMixin Function.

class A {
  a1: number
  a2: number
}

// Assigning transform properties to a class.
const B = TransformMixin(A)

const b = new B() // as A & Transform

b.translate
b.rotate

transform rotate scale skew origin rotateDeg (getter)

decomposeTSR // to decompose a Matrix into a Transform. (* in the order of transform, scale, rotate)

etc...

• methods to create a Transform Matrix. translation rotation rotationDeg scale skew skewDeg identity

• multiply mul compose

point // to apply the matrix to a point. points // to apply the matrix to points. smooth // rounding number etc...
