Hi all,

  I came across a bug in the delivered asdfly sample on IRIX platforms.
I'm working on ASD's and virtual clip textures. My textures did work
perfectly with clipfly but not with asdfly while in multipipe
environment. Looking trough the (dense) code I found that in the later
the textures are only loaded on the first pipe... Here is the patch to
make it work...

  HTH
