  2.     File:        CodecLibrary.h
  3.  
  4.     Contains:    Graphics library for QuickTime decompression of QuickDraw GX
  5.                 data.
  6.  
  7.                 This library uses QuickTime compression and decompression to
  8.                 image QuickDraw GX data. The basic technique is to encapsulate
  9.                 the QuickDraw GX image in a compressed data format using the
  10.                 object flattening functions from QuickDraw GX. Once the
  11.                 compressed image data is created, it may be passed to the
  12.                 QuickDraw GX codec and drawn using the QuickTime image
  13.                 compression functions or embedded within a QuickDraw picture
  14.                 and drawn using the DrawPicture function. In either case, the
  15.                 compressed data is passed to the the low-level QuickDraw
  16.                 drawing routines through the StdPix bottleneck routine. StdPix
  17.                 decompresses the data using the QuickDraw GX codec and passes
  18.                 the decompressed data to the bitsProc bottleneck routine when
  19.                 rendering the image.
