11 void al_invert_transform(ALLEGRO_TRANSFORM *trans)

14 Inverts the passed transformation. If the transformation is nearly
15 singular (close to not having an inverse) then the returned transforma‐
16 tion may be invalid. Use al_check_inverse(3) to ascertain if the
17 transformation has an inverse before inverting it if you are in doubt.
