Hi Brendan,

The pull request is now alive (refer to 769).

To select the 'fast' or 'exact' mode, there is an enumeration 'FinalizationFlags' (in 'include/OpenColorIO/OpenColorTypes.h') used by the method 'Processor::getOptmizedCPUProcessor()' (in 'include/OpenColorIO/openColorIO.h').

Please let me know if you have any questions.

Regards,
Patrick
