<!-- ##### SECTION Title ##### -->
GimpMatrix
<!-- ##### SECTION Short_Description ##### -->
Utilities to set up and manipulate 3x3 transformation matrices.
<!-- ##### SECTION Long_Description ##### -->
<para>
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.
