107
When doing image manipulation you will often need 3x3 transformation
85
108
matrices that define translation, rotation, scaling, shearing and 
87
110
find a set of utility functions to set up those matrices and to perform 
88
111
basic matrix manipulations and tests.
89
112
</p>
 
113
<p>
 
114
Each matrix class has a 2 dimensional gdouble coeff member. The
 
115
element for row r and column c of the matrix is coeff[r][c].
