Basic type: Compound linear transformation.
This class represents a linear transformation specified as a series of individual components: a translation, a rotation, a scale, a pivotPosition, and a pivotOrientation. When applied to a point, the point will be transformed as follows (in order):
That is, the cumulative matrix that this represents looks like this.
