2002-11-06 Sven Neumann <sven@gimp.org> * app/base/base.c (base_init): don't say we'd use MMX if it is disabled. * libgimpmodule/gimpmodule.[ch] * app/gui/module-browser.c: changed enum values and user-visible strings to saner values. * libgimpmodule/gimpmoduledb.c * plug-ins/tools/tool-safe-mode.c: made them less verbose.

Utilities to set up and manipulate 3x3 transformation matrices.

<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.
