Description
The Matrix class specifies transformation from one coordinate space to another.
These transformations include translation, rotation, scaling and skewing.
A 2D transformation matrix is a 3 x 3 matrix in homogenous coordinate system:

You can get and set the values of all six of the properties in a
Matrix object: `m11`, `m12`, `m21`, `m22`, `tx`, and `ty`.
Since Gideros 2016.6, Matrix can also hold 3D (4x4) matrices.
