Missed the man page (Sorry). The 2.4 release notes explain the changes in
pfdPrim and pfdGeom. For turning texture OFF you should now code:

  {
      int t;
      for (t = 0 ; t < PF_MAX_TEXTURES ; t ++)
        p -> tbind[t] = PFGS_OFF;
  }

All the texture related members of pfdPrim and pfdGeom are now arrays of
size PF_MAX_TEXTURES. This change is a part of the support for the OpenGL
multitexture extension.

Thanks for finding this,
