- Two instances of the same bug in ARM's code, where RenderSize was used instead of MaxRenderSize to calculate UVs
- One instance of me previously fixing a bug in Isonzo that isn't a bug in the latest PPV2 code, oops
Also disable writing to locks UAV at the end of Accumulate pass, as it doesn't actually do anything and it might cause issues with reading & writing to the same texture.
- Define macros for various VS/FS binding intrinsics
- Use pragmas to set output formats for render targets that aren't normal RGBA
- Added alpha channel to color output targets, so that they're 4-channel instead of 3
- Pass FSR2 constant buffer to reactive mask shader (may not matter)
- Removed "fix" to initialize params to 0, as that happens midway through the Accumulation process, resetting a lot of variables. Instead rewrote InitParams to take an inout parameter and clear the params first thing in the Accumulate function.
- Bind first multi-render target as depth target, fixes RenderDoc errors about color/depth buffer size mismatch.
- Ensure keywords that need a value are redefined using the correct value.
- Removed obsolete auto-TCR constants struct.
- Removed empty parantheses on GroupMemoryBarrier macro, which confuse the 2020.1 shader compiler
- Added padding field to cbFSR2 to make it exactly 128 bytes in size, which gives correct buffer alignment on iOS Metal
- Changed auto-exposure reset threshold value to 1e4f, as part of a fix for black screen flashes in OpenGL Core on Nvidia GPUs
- Clamp luma to >= 0 in auto-exposure to fix artifacting in OpenGL Core on Nvidia GPUs
- Removed #extension directives meant for GLSL, which cause shader compiler warnings in Unity
- Removed vk::binding directives, as they are only meant for Vulkan and don't mean anything to Unity
- Initialize inout struct as zero to stop Unity compiler complaints
- Renamed vertex main function to VertMain to prevent duplicate main function declaration
- Removed duplicate VertexOut struct declaration
- Removed unused header includes in vertex shader code, preventing duplicate declarations
- Fixed up a few relative header include paths
