Performers:

I'm trying to view a virtual clipmap with my 3-pipe Onyx iR using clipfly.
If I use only one pipe (-M 0) then everything works fine. But if I
let it use all 3 pipes the cliptexture starts to do, well, funky
things. The mipmap levels seem to appear at random locations and I
get pfErrors of "Invalid Texture Load".

Looking at the source to clipfly, it appears that it's setup to slave
the cliptexture between pipes as explained in the programmer's manual.
I've perused the clipmap docs, and see nothing that could explain this.

Questions are:

- is clipfly incapable of displaying a virtual clipmap on more than
  one pipe?
- can Performer display a virtual clipmap on more than one pipe?
- does anyone have some source snippets showing how they successfully
  set the pfuAddMPClipTexturesToPipes() in a slave fashion? Something
  a bit more specific (and less do-everything) than clipfly...

Thanks for any help!
