                            Module Quickdrw; Interface
*****************************************************************************

 This is the main module interface to the data stream interpreter.  As such,
 it will read individual opcode elements and the appropriate data 
 parameters associated with that opocode.  These are either placed into
 the CGrafPort structure or calls are made to the Gdi module to issue
 the correct metafile function.

   Module prefix:  QD
