Struct ClearColor 

pub struct ClearColor(pub Color);

A Resource that stores the default color that cameras use to clear the screen between frames.

This color appears as the “background” color for simple apps, when there are portions of the screen with nothing rendered.

Individual cameras may use Camera.clear_color to specify a different clear color or opt out of clearing their viewport.
