 This should all be rather straightforward: we define a `Settings` struct that stores the two values, implement the [`Default`](https://doc.rust-lang.org/nightly/std/default/trait.Default.html) trait for it, then define a two-element array with property metadata (names, description, ranges, default value, writability), and then store the default value of our `Settings` struct inside another `Mutex` inside the element struct.

 In the property setter/getter functions we are working with a `glib::Value`. This is a dynamically typed value type that can contain values of any type, together with the type information of the contained value. Here we’re using it to handle an unsigned integer (`u32`) and a boolean for our two properties. To know which property is currently set/get, we get an identifier passed which is the index into our `PROPERTIES` array. We then simply match on the name of that to decide which property was meant
