I depended on a warning from Paracomp (that pclib.conf) wasn't found for
ensuring that Paracomp was indeed being used.

Seem the same to me.

Didn't see anything useful there :-( Turned out to be a more difficult
exercise than I had expected.

Ok - here is one more try. I have copied the equalizer depth compositing
code itself into Paracomp (essentially a special case for debugging just
this case) & comitted the change (rev 63). Can you try updating to that
rev & run a quick performance test ?
