/*
* Debugging Variables
*
* Define one or more of the following compile-time variables to 1 to obtain
* elaborate information about certain aspects of the decoding process.
*
* DEBUG_VP3: high-level decoding flow
* DEBUG_INIT: initialization parameters
* DEBUG_DEQUANTIZERS: display how the dequanization tables are built
* DEBUG_BLOCK_CODING: unpacking the superblock/macroblock/fragment coding
* DEBUG_MODES: unpacking the coding modes for individual fragments
* DEBUG_VECTORS: display the motion vectors
* DEBUG_TOKEN: display exhaustive information about each DCT token
* DEBUG_VLC: display the VLCs as they are extracted from the stream
* DEBUG_DC_PRED: display the process of reversing DC prediction
* DEBUG_IDCT: show every detail of the IDCT process
