This also led to some reorganization of variables and event ordering.
Added some bloom to the post-process layer to test the cooperation between FSR2 and other post effects.
The way this works: compute luminance always outputs an auto-exposure value. The passes using exposure as input can either use this auto-exposure, or use the default read-only exposure value, or use an application-provided exposure.
- Implemented 1x1 exposure texture and bound it to the compute shader.
- Implemented RCAS config data set with precomputed values (so we don't have to do any unsafe float-to-int conversions), apply it to a constant buffer, and made sharpness available as a slider in the inspector.
- Yoinked a bunch of code from MadGoat SSAA to build a custom render scaler
- Added a simple shader to check some of the render buffers during upscaling
- Successfully ported the RCAS compute shader from the FSR2 project into Unity!
