-69- 1.2 libpf Transparency Sorting


  When the PFCULL_SORT mode of pfChanTravMode is set, transparent
  objects are drawn after all opaque geometry.  However, transparent
  objects are not sorted back to front among themselves, so visual
  anomalies can result when using blended transparency.  Workaround:
  use multisample transparency (PFTR_MS_ALPHA), if available.
