A small bug was introduced with the new dead zone code that made it ignore "quirks" regarding DS3/DS4. These devices should automatically be given a dead zone of 10, as it was before.
* Merge branch 'hdr' of https://github.com/wickerwaka/Main_MiSTer into feature-hdr
Merged in wickerwaka's old HDR branch and integrated the BT2020 and DCI P3 color space conversion matrices. Changed "hdr" option to be a selection of matrix instead of saturation option.
* Add HDR example to MiSTer ini
