I don't see why this is private. I would like to use it to add Graphics API specific to my default hints:
```zig
const defaultHints = .{
    .visible = false,
    .resizable = false,
};
const graphicsApiHints = .{
    .opengl_profile = .opengl_core_profile,
    .context_version_major = 3,
    .context_version_minor = 3,
    .opengl_forward_compat = true,
}
defaultHints.set(); // would like to do this
graphicsApiHints.set(); // would like to do this
// Create window...
```
