12
14 Returns the inverse of the current transformation of the target bitmap.
15 If there is no target bitmap, this function returns NULL.
16
17 This is similar to calling al_invert_transform(al_get_current_trans‐
18 form()) but the result of this function is cached.

20 Note: Allegro’s transformation inversion functions work correct‐
21 ly only with 2D transformations.
