Deflicker: mode switching: gui complete
DEFLICKER_MODE_SOURCEFILE is working?
Deflicker "Automatic" is working?
Speedup DEFLICKER_HISTOGRAM_SOURCE_SOURCEFILE by caching histogram
Dynamically set request_histogram and request_histogram_source fields in each commit_params() call
e.g. in DEFLICKER_HISTOGRAM_SOURCE_SOURCEFILE, in-pipe histogram is no longer being computed.
wip
Move DEFLICKER_HISTOGRAM_SOURCE_SOURCEFILE correction computation into commit_params
Refactor common code into commit_params_late()
