Currently, commute_ppr (#1563) considers only commutes P(pi/4). However, P(pi/2) can also be commuted. The catch is that it applies a different commutation rule from P(pi/4)P', so if the rule for P(pi/2) states that PP' = -P'P, then: P(pi/2) P'(x) = -P'(x) P(pi/2).

This support should be extended to commute_ppr.
