[Sidefx-houdini-list] point cloud in shader to live operator

I believe Houdini itself supports the op: syntax on point clouds.  But
not necessarily in mantra.  Mantra doesn't know about the nodes in
Houdini.  So, you can use op: in SOPs or wrangles, but not easily in

On the other hand, in H16, if the op: path specifies the path to a
SOP, AND, the SOP is sent to the IFD (i.e. rendered), then I believe
the op: syntax should work in mantra now.  The hairgen/groom process
uses this.
