+<p>When doing image manipulation you will often need 3x3
+transformation matrices that define translation, rotation, scaling,
+shearing and arbitrary perspective transformations using a 3x3
+matrix. Here you'll find a set of utility functions to set up those
+matrices and to perform basic matrix manipulations and tests.</p>
+<p>Each matrix class has a 2 dimensional gdouble coeff member. The
+element for row r and column c of the matrix is coeffr.</p>
