This check in includes quite a lot of clean up and refactoring. Most of the analysis and set up for the different coding options for the segment map (currently simple distribution based coding or temporaly predicted coding), has been moved to one location (the function choose_segmap_coding_method() in segmenation.c). This code was previously scattered around in various locations making integration with other experiments and modification / debug more difficult. Currently the functionality is as it was with the exception that the prediction probabilities are now only transmitted when the temporal prediction mode is selected. There is still quite a bit more clean up work that will be possible when the #ifdef is removed. Also at that time I may rename and alter the sense of macroblock based variable "segment_flag" which indicates (1 that the segmnet id is not predicted vs 0 that it is predicted). I also intend to experiment with a spatial prediction mode that can be used when coding a key frame segment map or in cases where temporal prediction does not work well but there is spatial correlation. In a later check in when the ifdefs have gone I may also move the call to choose_segmap_coding_method() to just before where the bitsream is packed (currently it is in vp8_encode_frame()) to further reduce the possibility of clashes with other experiments and prevent it being called on each itteration of the recode loop.
