Peter Hallett, of Precision Visuals, states that:

  It is incorrent to state that PV~WAVE is a shell that sits on top of IDL.  
  Essentially, PV~WAVE is a superset of IDL.  Currently, IDL procedures 
  and applications will run using PV~WAVE.  

My question is: Does PV-Wave extract some sort of performance penalty
(in terms of speed) by riding on top of IDL.  One of my friends
compared IDL and PV-Wave several years back and found that IDL
seemed to run much faster than PV-Wave so they went with IDL.
Is this still true?  Does PV-Wave cost me anything relative to 
IDL (except for more $)?  Are there things I can do in IDL,
but not in PV-Wave?  My target platform is a Sun 4 workstation.
