 astInvert 
   Invert a Mapping  
      
Description: 
 This function inverts a 
Mapping by
reversing the boolean sense of its 
Invert attribute. If this attribute is zero (the
default), the Mapping will transform coordinates in the way specified when it was
created. If it is non-zero, the input and output coordinates will be inter-changed so
that the direction of the Mapping is reversed. This will cause it to display
the inverse of its original behaviour.  
Synopsis

this )
 Parameters: 
  this  
 Pointer to the Mapping.
