Quicksort [ Small { Unseen } Big . Pivot ]
    
Last column:
 (  invocation of quicksort procedure
 )  exit from quicksort via the base case
 )+ exit from quicksort having done some work
 {  the iUnseen pointer '{' was advanced
 }  the iBig pointer '}' was advanced
 P  pivot was moved to its place between the Small and Big regions
 S  the Small region is now sorted

Within array:
[   iBegin
]   iEnd
{   iUnseen
}   iBig
|   overlap of iUnseen and iBig
.   iPivot
>   left entry to be swapped
<   right entry to be swapped
=   entry to be swapped with self
