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.
With Cemu 1.15.12 's gl_PointCoord support, night stars now have proper (varying) alpha value. Should be no need for workaround anymore, just scale its size accordingly.
Add: Scaling of world map
Add : 16:10 resolutions
Add : x2 SSAA vert res for 21:9, 48x9
Fix : Better alpha for x2 Subres, rounds to native x2 if possible
The game re-applies a cropped 1280x400 background in order to create the fading on the inventory borders. Not resizing it causes the background especially Link and items he is holding to become blurry and aliased mid-screen with two cutoff lines. This rule was present in pre-1.14 rules.
Also updated the skylander game's statuses in the list.
They did do some optimizations. Also, the music is so god damn repetitive, I think I've listened 1 hour of what felt like a 30 second music loop...
Still an improvement over the 720p resolution even though most of it is hand-drawn. The assets are actually far more higher-resolution then the game renders them at.
Removed the resolution ratio indicators since it's not needed if there's no other aspect ratio resolution available, also removed the disclaimer about not being able to change them on the fly since Cemu warns you via it's interface already when you change a preset on rules.txt with texture redefine's
Probably the easiest version 3 resolution pack to make! No viewports with some margin or half-res stuff, 2 formats for all of it's rendering (doesn't even blur by downscaling viewports)...
Also added a shader edit for the background, just because. This game is also pretty cool.
Previously wouldn't show puzzle pieces in the level selection screen.
The texture that would also need to be scaled is 0x033 which is a compressed texture which can't be scaled, so removing this filter was the only option. But this was mostly pointless anyway since the GUI is also just images which won't really become sharper.
