void al_transpose_transform(ALLEGRO_TRANSFORM *trans)

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