Just to confirm -- looking through the code checked into 2.2.3 for
this, it appears to only address the PFFRUST_ORTHOGONAL case; there
were no changes that I see for asymmetric frusta.

(performer_eoe 2.2.3 will ship with IRIX 6.5.2 overlay and also as a
 new patch for IRIX 6.2-6.4, both to be released soon)
