cglm has two options for representing a vector: using a struct and using an array. The default one is using an array, but I'm not seeing what are the benefits of using an array instead of a struct. When using an array, you need to use out parameters, which make the code much more ugly when doing multiple operations. Using a struct, I can simply return the struct from the function. The only advantage of using an array would be that it's easier to iterate through it, but I could do the same using structs like this
