Billy Laws b4a12b889e Avoid using VectorExtractDynamic for subgroup mask on Adreno GPUs 
This crashes their shader compiler for some reason.

Billy Laws 158a1896ec Implement scaled vertex buffer format emulation 
These formats are unsupported by mobile GPUs so they need to be emulated in shaders instead.

Wollnashorn fe91066f46 video_core: Enable ImageGather with subpixel offset on Intel 2023-04-08 16:12:44 +02:00
Wollnashorn 780240e697 shader_recompiler: Add subpixel offset for correct rounding at ImageGather 
On AMD a subpixel offset of 1/512 of the texel size is applied to the texture coordinates at a ImageGather call to ensure the rounding at the texel centers is done the same way as in Maxwell or other Nvidia architectures.
See https://www.reedbeta.com/blog/texture-gathers-and-coordinate-precision/ for more details why this might be necessary.

This should fix shadow artifacts at object edges in Zelda: Breath of the Wild (#9957, #6956).

Billy Laws bbfad79c89 Vulkan: Add a workaround for input_position on Adreno drivers 
Adreno drivers will crash compiling geometry shaders if the input position is not wrapped in a gl_in struct.

ameerj b84d429c2e glsl_context_get_set: Add alternative cbuf type for broken drivers 
some drivers have a bug bitwise converting floating point cbuf values to uint variables. This adds a workaround for these drivers to make all cbufs uint and convert to floating point as needed.

ReinUsesLisp 916ca74324 opengl: Declare fragment outputs even if they are not used 
Fixes Ori and the Blind Forest's menu on GLASM. For some reason
(probably high level optimizations) it is not sanitized on SPIR-V for
OpenGL. Vulkan is unaffected by this change.
