Detailed Description

Homogeneous 2D transformation matrix.

This is a 2x3 matrix representing an affine transformation on the R^2, in the usual C/C++ row major form. It is structured as follows:

a b t_x
c d t_y
0 0 1

where the lowest line is not stored in the matrix, since it is constant. Variables t_x and t_y contain translational components, a to d rotation, scale and shear (for details, look up your favorite linear algebra/computer graphics book).
