The 2D Matrix is an object for holding values for an affine transformation matrix.
The 2DMatrix is created by Titanium.UI.create2DMatrix. A 2D matrix is used to rotate, scale, translate, or skew the objects in a two-dimensional space. A 2D matrix is represented by a 3 by 3 matrix. Because the third column is always (0,0,1), the data structure contains values for only the first two columns.
You create an identity matrix by creating a 2D Matrix with an empty constructor.
