NAME
       al_transpose_transform - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro.h>

              void al_transpose_transform(ALLEGRO_TRANSFORM *trans)


DESCRIPTION
       Transposes the matrix of the given transform.  This can be used for
       inversing a rotation transform.  For example:


              al_build_camera_transform(camera, 0, 0, 0, x, y, z, xu, yu, zu)
              al_copy_transform(inverse, camera)
              al_transpose_transform(camera)
              // Now "inverse" will be a transformation rotating in the opposite
              // direction from "camera". Note that this only works if the camera
              // position is 0/0/0 as in the example.
