[Request] Port CRT-Beam shader to Slang

[HitoriSensei]

I've seen CRT-Beam (https://github.com/libretro/glsl-shaders/blob/master/crt/shaders/CRT-Beam.glsl) on ScummVM and I was astonished how great it looks on 4K HDR together with Normal2x pre-filter (to simulate double-scan CRT).

After research in the shader I've found that ScummVM shaders are actually from libretro project so I've tried find and apply it to my RetroArch configuration.
Then I've noticed that it is only available as GLSL, which cannot be used with Vulcan driver unfortunately.

Would there be a possibility to port the shader to Slang?
