- blcDiffMB_t is used as a temporary storage for the previous difference
- (INTER) macroblock. This storage is needed for the Advanced Prediction
- mode because the previous prediction macroblock cannot be constructed
- until the motion vectors of the current macroblock have been fetched
- from the bitstream. (The previous difference macroblock cannot be stored
- directly to the current frame either, because the difference block data
- is signed and the frame data is unsigned.)

- This C preprocessor definition is used to store the parameters needed
- for the blcCopyPredictionMB function (and therefore also for
- the blcCopyPredictionMBParam_t data type). These parameters may also be used
- in other modules than the Block Tools and in other data structures than
- blcCopyPredictionMBParam_t. When these parameters are introduced with this
- preprocessor definition in the other data structures, one does not need
- the "extra" reference step which would be needed if the parameters
- would have been introduced directly and only in
- the blcCopyPredictionMBParam_t structure. For example, if otherStructA
- has been typedefd as {BLC_COPY_PREDICTION_MB_PARAM} and otherStructB as
- {blcCopyPredictionMBParam_t predPar;}, to access e.g. refY one has to use
- either otherStructA.refY or otherStructB.predPar.refY.
