Adds an option controlled by a macro to replace one of the guided filters in the self-guided tool with a simple bandpass filtered version generated with a 3x3 kernel. By default the macro USE_HIGHPASS_IN_SGRPROJ is 0 (turned off), that defaults us to the dual self-guided filter. When the macro is turned on, the larger radius guided filter is replaced by a simpler filter that is much faster. Results (if USE_HIGHPASS_IN_SGRPROJ is on vs. off): lowres: performance drop by +0.14% (BDRATE) midres: performance drop by +0.27% (BDRATE) Further experiments on this variation of guided filters is pending.
