Subject:  -117- 1.0 Bug in pfInitGfx() with Z-buffer on RealityEngine
Date: 26 Oct 93 00:00:01 EST

  pfInitGfx on RealityEngines would call lsetdepth(0x0, 0x0),
  essentially disabling zbuffering.

  The workaround was to call lsetdepth explicitly after pfInitGfx, in
  the pipe initialization callback.
