I searched through quite a bit of commits to properly credit some packs. Some of the credits are based off memory. Please let me know if I incorrectly credited or forgot to credit somebody.
Basically, the code previously would always replace the ratio calculation code for the 3d rendering and just load the upscaled width divided by the upscaled height. But the code gets passed other aspect ratios too, for example in the gear menu (and very likely other menus too).
So, even when users didn't use an ultrawide aspect ratio it would set the aspect ratio of anything that was 3d rendered to be 16:9, basically.

I made some assumptions about the other game versions regarding the floating point register that I use to load the scale float into, which is free to use in the EU 1.0.1 version at least.
I assume that the code for all of this is would be very similar though, since the previous ratio patch only had some addresses change across versions so it's probably fine.
This actually properly fixes https://github.com/slashiee/cemu_graphic_packs/issues/334 which was closed without any proper solution. Someone reported the issue in the Cemu Discord which made me fix it, since I thought the issue was addressed already.
Xenoblade Chronicles X packs are now ported too! Which has, after BotW, the most shaders I think made by all of the efforts from getdls. All shaders were successfully verified and tested in-game (from what I could tell).
Since it's not possible to update 300+ shaders manually and automation was possible, I thought that I'd take the honor and create a script that's able to automatically convert all of the shaders to be cross-compatible with Vulkan. And change the graphic pack versions to version 4 of course.
Also, the script has some nifty testing code which compiled every shader as OpenGL and Vulkan, but for that see the details that I've written below.
**Here's the script that I've made to do all of this. No manual edits were needed:**

Since I wanted to make sure that I didn't broke the shaders after converting the shaders to Vulkan, we need to check if all the shaders weren't broken. Since we're talking about like 400 shaders checking all of them is pretty much impossible and even then,
So, the obvious solution was to automate the checking. Not as simple as you'd think, because in 300 of our shaders we use preset variables which without replacing the value like Cemu does, will make the shader error regardless. So I also implemented some functionality that would read the preset values and types out of the rules.txt file and replace them in the shaders using that information. And then we use Khronos' glslang to compile the shaders, using both OpenGL and Vulkan.
The result was that glslang found quite a few errors in some of the shaders, which I fixed in this commit. I'm considering adding this rules.txt parsing and automated shader compilation testing to the build process.
Also, I fixed Clarity's name and description since Monochromia isn't available anymore and Xenoblade's resolution pack had a lot of weird blank lines before their #version declaration, which my converter didn't like.
Re-adds custom shaders removed in red-sky fix as enhancements

Baseline is: Works on nvidia. Intel/AMD/3dfx/Integrated GPUs, not my
problem.
