commit fc5506c7906bf82d6f88b7b0d7e4764d58d90622
Author: Ophidon <jrogers2@gmail.com>

BFI Updates
Significant BFI updates.
- Adds BFI to dx10/11/12 in general.
- Updates existing BFI menu option descriptions to be somewhat more clear in how to use correctly.
- Adds Variable Strobe length via new 'Dark Frames' bfi sub-choice. Only valid at 180hz and above, as it must work with whole frames.
- Algorithm to auto select 'decent' Dark Frames choice, for any given selected BFI refresh rate. Will also avoid defaults that can cause Image Retention at any Hz higher than 120. (Impossible to avoid at 120 if you have an affected screen... get an OLED :D ) .
- Some sanity checking on selecting BFI or the other synchronizations options like Swap Interval > 1, that don't play well with BFI.
