Windows purego errors

[wizzymore]

I am using the release of raylib from: Nov 18, 2023, i tried with both x64 versions they do the same thing.
I also tried to build the app and it works, the build is ok this error appears only in the runtime.

> go run .

Hey @wizzymore,
if you use the raylib-go version from Nov 18, 2023 (tag: raylib/v5.0.0), you also have to use purego v0.5.0:
https://github.com/gen2brain/raylib-go/blob/raylib/v5.0.0/raylib/go.mod#L6

purego has a runtime check in v0.7.1, which doesn't allow you to use structs.

For raylib-go (at least for the purego version) I recommend you to use the latest version (v0.0.0-20240826113553-b4d0c52dc927), because we fixed many bugs since then.

Thanks, just updating the package seems to fix most of the issues i had, still i have pure-go 0.7.1, i don't know how to use another version as installing 0.5.0 uninstalls raylib-go

The only bug that i found, surprisingly not in shaders or other more complicated logic, it was with ColorFromNormalized function:

Let me know if you want me to create another issue for this error, i will close this one, thanks again.
