#include \f[B]<allegro5/allegro.h>\f[R]

void al_transpose_transform(ALLEGRO_TRANSFORM *trans)

.SH DESCRIPTION
Transposes the matrix of the given transform.
This can be used for inversing a rotation transform.
For example:
.IP
.EX
al_build_camera_transform(camera, 0, 0, 0, x, y, z, xu, yu, zu)
al_copy_transform(inverse, camera)
al_transpose_transform(camera)
\f[I]// Now \[dq]inverse\[dq] will be a transformation rotating in the opposite\f[R]
\f[I]// direction from \[dq]camera\[dq]. Note that this only works if the camera\f[R]
\f[I]// position is 0/0/0 as in the example.\f[R]
