FO4VR Contrast Adaptive Sharpening v2

Changes (as contributed by https://github.com/padutilleul):

• enable higher-quality sharpening over diagonals in the shader
• add an option to limit the max amount the sharpening filter can modify an individual pixel. This can be used to prevent issues of oversharpening, for example with flora in Skyrim VR. Note: this feature is disabled by default, you need to modify the "maxColorDelta" value in the config file. Set it to e.g. 0.07.

FO4VR Contrast Adaptive Sharpening + Controller fix

Image sharpening post-processing filter for FO4VR which improves image clarity. Combined with the original Index/Cosmos controller fix (which may no longer be needed on the latest SteamVR version).

Controller fix with Contrast Adaptive Sharpening

Added AMD's FidelityFX Contrast Adaptive Sharpening as a post-processing effect. Configurable via settings file.

FO4VR Index Controller Hack v1.1

Quick workaround for an apparent SteamVR bug. For instructions, see v1 release.

FO4VR Index Controller Hack v1

This is a quick and dirty hack to "misreport" the Index controllers as Oculus
touch inputs to get usable controlls in FO4VR. Just grep the openvr_api.dll
and copy it into your Fallout 4 VR dir, overwriting the one already there.

Note: you still need to modify the SteamVR controller bindings for Fallout 4 VR,
because the default legacy bindings are not suitable. Open the SteamVR dashboard,
go to Settings -> Controller Settings, select Fallout 4 VR in the list on the
right. See if you can find my customized bindings (by CABAListic).

If not, edit the default legacy bindings. Here's what you need to do:

1. remove the "Use as button" action from both thumbsticks.
2. modify the "A button" mapping for both controllers to map to the
   "left/right A button" instead of grip.

Save the bindings. You should be good to go.
