// If a user has a non-legacy skin (argon, triangles) selected, the game won't normally fall back to a legacy skin.
// In turn this can create an unexpected visual experience.
//
// So here, check what skin the user has selected. If it's already a legacy skin then we don't need to do anything special.
// If it isn't, we insert the classic default. Note that this is only done if the beatmap seems to be providing skin elements,
// as we only want to override the user's (non-legacy) skin choice when required for beatmap skin visuals.
